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.

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.
56-1/2", 58-1/2", and 60-1/2" kits are now shipped as two CNC formed 90 degree sections. 62-1/2" kits are shipped as flat plates, for now. What appears as lines in the pictures are actually laser-cut slits in the plate. These slits make it easy to form the piece by hand, or, in some cases, 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.
