74 - 78 Mustang II front suspension

Been offered a complete front including crossmember and power rack, all A arms etc.

What's the feasibility of grafting onto an AD frame.?

Re: 74 - 78 Mustang II front suspension

IMO, it can be done but it's problematic and lots of work. The way the cross member and suspension hats intersect the frame makes them need to be in two pieces which, in factory form, they are not. And, you can't usually use the aftermarket cross member with the stock suspension stuff because most of the time the control arms won't fit, especially the lowers. About the only useable part could be the rack, unless you have way more time and talent than money. I bought an unfinished project where someone tried to use the stock stuff. It was horrible to the point where it was never correctly finished. A bunch of cutting and an investment in some Heidt's stuff and it turned into a pretty sweet ride.

Here's what I was thinking; on the stock crossmember the width is 27 1/2 ", frame is about 28 1/4, tapering to about 27 1/2. I would slightly notch the stock "towers" on each side and weld in, then weld on the brackets for the rear trailing arms.

I don't think you're asking but I'd say don't do it. Sure, anything can be done with enough effort and fabrication but SHOULD you do it? I'd say no off hand unless you're very knowledgeable about suspension geometry, anti dive, etc.

Re: 74 - 78 Mustang II front suspension

what about buying a cross member for $300 from Speedway, meant to go into your truck, then bolting the rest of the mess onto that?

Re: 74 - 78 Mustang II front suspension

Keep in mind when people these days refer to a "Mustang II" front suspension for these trucks, they aren't talking about an actual suspension from a Mustang II. That just refers to a general style of IFS design for aftermarket built kits, typically, not the use of parts right off a Mustang II.

Re: 74 - 78 Mustang II front suspension

If you factor in your time and the amount of work it will take, along with all the problems you are probably going to run into using an original Mustang II ifs, you will be money ahead buying an aftermarket IFS from any of the big manufacturers. Plus they've all put a lot of time into R&D so they'll handle a lot better, look nicer and last longer than anything OEM.
