Thread: IFS question

Tweet

I'm working on a 30 ford roadster with a 350, it came with IFS from a mustang 2 .The car is fenderless and I would have preferred a straight axel, but it drives good so I thought I'd leave it for now. The stock IFS system looks tacky sitting right out ther in the open, so I thought I'd put tubular arms on it. I bought a set of 4 from a local dealer, the top arms look like they'll bolt right on, but the lower ones look like they have to fit on the out side of the pivot mount? My question is, does the new lower A arm mount on the outside of the pivoting area? or do I have something wrong? This is my first hotrod, I'm pretty green.

O.K., let's start from scratch. The car has an original MII setup on it, right? That system is where the lower arm is a single arm that pivots inside a crossmember and sits 90 degrees to the centerline of the chassis rails. Another single arm runs from the lower arm at the spindle back to the frame rail at about a 45 degree angle to the centerline of the chassis rails. Does that describe your setup? What is the measurement between the control arm bushing bosses on the new bottom arms you bought?

Thanks for quick reply- Yes I was told this is from a stock mustang 2. The first part of your desciption seems correct, the lower arm fits between the crossmember, but nothing runs up on an angle, the top arm operates parallel to the lower one. The lower one is 13 " long-pivot to spindle mount- the top one is shorter. The width of the new lower one is 10.5", thats at the end that mounts to the crossmember.
All the measurements look correct with the new set, except were the lower one connects to the crossmember, it looks like it mounts on the exterior of the crossmember, instead of the inside like the one on the car.
Hope this explains it better. Thanks Rod

Yeah, this is an aftermarket kit to eliminate the strut rod. Who manufactured the arms you bought?

A photo would help also.

If this is the type of lowers you have, it is going to take some reworking of the crossmember to make them work on a stock MII crossmember.....

The second pic should give you an idea of what the assembled front end and crossmember for the wider lower arms would look like.....

There is no name on these parts, or instructions, but I think I'm getting the picture( thanx for the pictures). I believe I'll have to do a fair bit of modifacations to get the lower arms in, including messing with the steering.
Now I'm thinking of only installing the top arms, Will that work?

As long as the dimensions are the same and the ball joint has the same taper you should be ok.

This is also my first time on a forum, I'm impressed, you guys have been super helpful thanx.
