Suspension for 1976 vega

Postby crazyman312 » Tue Dec 30, 2008 8:46 pm

i am building a 1976 vega with a 4.3L v6. i need to know if the suspension off a 1997 S10 will fit. Also if the rear end will fit. If you can give me any pointers as to building it with a V6 that would help also. Thank You

Welcome to the site!

You can adapt the S10 spindles to the Vega a-arms by using ball joint conversion bushings or modifying the control arms for the S10 ball joints. The upper and lower a-arms from the S10 mount differently and would take extensive mods even if it was possible. A '76 Vega has a 6.5 torque arm rear axle. You could weld the mounting brackets from the Vega to the S10 rear axle but you would have to fabricate a mount for the torque arm to the axle. An easier method would be to find a Monza 7.5 axle, use 26 spline early S10 axle shafts or modify the 7.5 to use the 28 spline carrier and axle shafts.

ok. i am planning on making the vega a 5 lug. So what year is the cut off for an s10 that would basically bolt up with little modification? here is some pics of the vega:

I'm with Dick on the Monza 7.5" housing and swap in the insides from the S10. You have to get the pinion tuned down to match the monza bearings. I think Jim does this at JDrace.com. He's a fellow H-buddy. You'll need the Monza axle housing, Panard bar, and torque arm. Is the trans still in it? Is it stick?

It looks like you've got your work cut out for you. I noticed another Vega door in one of the pix. How many are there?

The fronts are a bit less complicated… sort of. The parts that swap are the spindles and brakes. You should grab that master cylinder while you are at it. OH you can swap in the rear drums too. No need for fabrication for the rear since you have the later chassis you'll have the panard bar mount. SO it's just the irritation of setting up a rear diff. The front you can use the Monza ball joints and get Bob Gumm's adaptors for the spindles or fabricate new mounts for the S10 ball joints. That's a little more complicated. There is a bunch of discussion on this topic in the "Best of"

The S10 in the picture looks like a 4WD. If it is the rear axle shafts will be too long for the Monza 7.5 and the axle housing, if you put the Vega brackets on the S10, regular wheels will stick out of the wheel wells. The front S10 4WD spindles will not work.

Where are you located?

I am in Rhome, texas. The door i have two spares same color and everything. the S10 is 2wd. If we can find a aluminum cylinder head for the vega (found out the car is a 1977 btw) we are going to rebuild the Engine and use it. No tranny came with the car but it had the 2.3 2300 4 cylinder. I tried edelbrock they told me to call cosworth. they told me good like on trying to find one. If any of you guys know where i can get the head i will build the original motor with performance parts but if not i can buy a complete suspension and a 9 inch ford rear end out of a 1974 vega already modified for a V8 for 500 bucks.

There are Cosworth heads available but you will need more, a cam carrier, cams, pistons, possibly a crank (depending on whether you build a 2.0L or a 2.3L), intake system, exhaust header. If you are trying to do it inexpensively, the V8 is the way to go. Cosworths are not cheap to build.

How is the floor pan? Most cars that sit like that are rotted out.

I think that you can use the axles from 2wd s10's up to 1992.[Standard spline of 26.] Also there are 2 standard vega cylinder heads on craigs list, one rebuilt in NJ and the other in CO.They are steel not aluminum, that is normal for the vega 2.3

Hey crazy
That 74 9' rear while not have the torque arm mounts on the differential housing.They can be fab up if you really want to go that route.76 & 77 vegas had the monza suspension which had the torque arm to replace the upper control arms and a panhard bar to keep the rear centered.Panhard mounts while need to be added also,to both the chassi and the dif.
