Problem Solving Hot Rod Chassis Parts Since 1978
High quality and low cost is achieved by using this Mustang II crossmember and upper tower kit. Set up the front end at the ride height you want! Detailed installation instructions are also online by clicking the link below. Either manual or power steering can be used- the passenger side mount has a slot to take the later model power rack. As with all Mustang II aftermarket crossmembers, spacers must be used with the later (Fox-body) power rack. These spacers are available in the Related Parts list at the bottom of this description. Use stock control arms or aftermarket upper and lowers with this kit.
Welder Series has a free service to help builders lay out the crossmember and upper tower cut lines. Click here for the work sheet. If you fill them out, take pictures of them, and email the pages back to us, we will give you drawings showing the sections to be removed. These worksheets can also give us the info we need to provide you with boxing plates. We’d give you a price for the plates and you can decide if you want to order them or make your own.
Please scroll to the bottom of the description to see related items like a lower A arm mounting kit, rack spacer kit, C notches, shock mount plates and caliper brackets.
Most vehicles will use the standard 56-1/2” track width. 1942-52 Ford pickups should use the 58-1/2” kit. Ford F100 (’53-’56) and 2nd series ’54-’59 Chev pickups should use the 60-1/2” kit. If you specify a welded kit, the corner-to-corner welds are neat but not ground.
All kits are now shipped as two CNC formed 90 degree sections. What appears as lines on the rack mounts are actually laser-cut slits in the plate. These slits make it easy to form the piece by using an adjustable wrench to get a better grip on a small tab. Rack mounts are incorporated into the crossmember design and rotate the rack back 20° to get the input shaft lower. Stock, manual or power racks or later model Mustang II or T-Bird power racks can be used. The later power rack will require the Power Rack Spacer and longer bolts, as described in the power rack mount spacer section. The rack is positioned so the bellows will clear most aftermarket full A-Arms (such as Heidt’s, Total Cost Involved, Fatman, etc).
Stylish, cone-shaped stamped upper shock mounts also function as the coil spring locator. The upper towers have anti-dive built in. The holes for the lower control arms are 5/8". Installation instructions show how to set up the front end at the ride height you want. Rack extenders or Fairmont tie rod ends must be used on 58-1/2″, 60-1/2", and 62-1/2″ kits. Crossmember & upper towers are made from 3/16″ mild steel. The track width is measured at the rotor wheel mounting surface. The width will vary, depending on the brake kit used. Please note: lower control arm pivot tubes and gussets are not included.
Track width is the rotor wheel mounting surface to surface dimension. Welder Series makes 3 widths: stock (56-1/2″), and 2″, 4". and 6" wider (58-1/2″, 60-1/2", & 62-1/2″). These are nominal dimensions. The final track width is dependent on the control arms, wheels, and brake system used. An easy way to estimate the stock track width is to measure tire tread center to center.The outside frame width is less critical than track width, but is a consideration. Our 56-1/2″ kit likes a frame o.d. of 26″ – 30″. The 58-1/2″ kit likes 28 – 32″. The 60-1/2″ kit likes 30 – 34″. The 62-1/2" kit likes 32 - 36". If the frame doesn’t correspond to these dimensions, there are work-arounds that we can suggest.
Do you need to cut your coil springs? Here's a helpful video from Eaton Detroit Spring: https://youtu.be/RNOmTsmABIc. Remember; as you cut the coil, the spring rate goes up (stiffer ride). Eaton Detroit also has short springs for Mustang II applications.

Every customer is different. You’re different from the next customer. That’s why they’re called 'custom'ers. There is no formula, no equation that will work with all of you. It takes a different approach to everyone to determine how best to serve anyone. Some people need videos, some people need descriptions. Some people need us to weld it together. Our approach has been, and will always be, to serve each of you where you are and to treat you the same way we would like to be treated. We officially opened the doors to Welder Series in 2005. That doesn’t sound like very long, because the product line has been percolating for over 40. Paul Horton began developing and building many of the parts we still manufacture when I wasn’t yet a twinkle in Dorothy’s eye. Thanks very much for your business and support over the years.

Note DW and Paul Horton at Welder Series absolutely rock and were quick, prompt, by far the best communication I’ve had with an online vendor in a LONG LONG TIME… (Sorry but their response time was bar none awesome). Very rarely do you find the level of dedication to a customer, communication, and a rewarding experience for both the buyer and supplier. I bought a pedal assembly a bit ago, and that experience automatically ensured that I will source Welder Series before I search for another vendor. Paul and DW have it together and will make a solution to your problem… and probably at the best price around to boot.
I have purchased a few of the products that Welder Series offers and been pleased each time. The products are as advertised and they ship in a timely manner.
I am also impressed with their customer service. I asked them if they had a brake pedal kit (mount, pivot, pedal, bushings, etc) for a right hand drive application. They did not have a kit per se but were able to put together pieces from their catalog to make one I could modify the Master Cylinder mount to make it face the other way (I had to cut the top off and weld it back on facing the other way, cheaper than ordering a one off part, and I don’t have a way to bend metal that thick, everything else fit up as intended). It worked as they described.
I just finished installing a Welder Series rear sway bar kit over the weekend. My all-steel ’35 sedan handled in the traditional “scrape off the running boards” way… even with a front sway bar. The kit went together nicely, everything fit perfectly and now the car goes around a corner 100% better… no more extreme lean. DW was a huge help in putting together a little bit different kit for me since I am using a tubular rear crossmember and also made some suggestions that really helped in the fabrication. You can depend on these guys… they are “for real” hot rod guys that offer really cool products. I’ll post a picture or two when I get the chance to put the car on a hoist for a better photo op. Thanks DW & crew.
