I am in the proces of doing a complete restoration on my 1975 Monza. I read that the reason for the negative camber issues with the s 10 swap is because there is negative camber built into the spindle. Is this why? Does anyone know how much negative camber is built in to the s-10 spindle?

I have done the conversion, and I've had no alignment problems. I know there have been threads on this topic, but I've been fortunate to not have this issue.

But of course, I did plan ahead. I needed new balljoints, so for the uppers, rather than pay big $$$$ for Vega units, I used S10 balljoints. At that time, I moved them out (to improve camber) and back (to improve caster).

My alignment guy was able to get it all in spec, and even was able to lay the caster back a little more than stock. It's good at 105 mph.

Josh seems to have found the simplest solution to the negative camber issue; I think I'll do the same thing. I wonder if Bob Gumm will refund half my money if I return just the upper ball joint adapters? :wink:

how much did you move them in either direction. It seems that you would not have to move them much

Josh; have you got a diagram with direction's / orientations and maybe a picture,,, we have seen a couple arround here from time to time.,,,, but some how I was under the "maybe false" impression that you moved the lower ball joint in toward the engine bay on the :arrow:

lower control arm (LCA) also the looking in thru the out side looking in at the spindle top "leaning back" of the spindle from the top toward the fiirewall is made to keep the car from going into a death wobble but what do I know,,, :arrow:

is it that much diference on the S-10 spindle, ??? :arrow:

Did I have it wrong??? Mike :oops:

EDIT; My apolgy you meant the :arrow:

top control arm didnt you Mike :oops:

The adaptors are for the lower balljoints, not the uppers.

Yes Mike, it was the upper balljoint.

I remember seeing someone doing the same kind of thing to the upper, but that's something I wouldn't ever want to do being that I'm not a professional welder. I modified the upper since it was just hogging out a hole. I wouldn't ever cut a high-load part like that and weld it back together.

And I did move it back to get rid of the wobble at high speed. Even the 1/2" or so I moved it doesn't seem like much, but when you consider the length of the spindle and the orientation, a 1/2" would come out to a couple degrees. And I do know it's good from the track last week, 105 mph and smooth sailing even after I applied the brakes.

upper ball joints for 80 dollars each.

Installing the S10 uppers are pretty easy. Here's a pic of the ones I did:

Taken from my front suspension page: http://www.cardomain.com/ride/2357894/5

Back when I made them I added in more negative camber and caster (a tiny bit more) but that was before I heard about the extra negative camber problem. SHIT! Anyway I ended up buying these to fix the problem.

I got them from Chuck Larsen. Fellow H-buddy member:

Here's me having "special time" with them. LOL!

I was planning on chucking the ones I built. I suppose they could be useful to somebody out there though. I've already pressed in the urethane bushings... Let me know...

Clyde bobs adapters are top and bottom i have them in my 72

Yeah, I found that out after I posted. For some reason I thought they were just needed for the lowers. Thanks for setting me straight...........

What you want for those I might be interested?

by **NixVegaGT** » Wed Dec 19, 2007 9:51 am

Cover shipping and an extra $20 for the bushings and they're yours. They are already pressed in and everything.

The bushings and ball joints are worth more than that. Better jump on that, vegafrog.

Nic, if I'm reading correctly you added negative caster plus with the S-10 spindles having negative caster you'd end up with alot of negative caster. (sorry if I sound negative,lol) What did you plan to do to correct that before you got the adjustable control arms? I'm just curious because I'm going to do the spindle swap eventually. I'm going to try to put some positive caster into the control arms when I put the ball joints in but just incase it's not enough I'm looking for solutions.

by **NixVegaGT** » Wed Dec 19, 2007 6:12 pm

I meant I moved the ball joint back for more high speed stability. Is that negative or positive? SO that part I did right. The assumption that the spindles were the same for the camber is where I messed up. SO these UCAs will have too much negative camber BUT if somebody hasn't welded in the LCA sleeve they could move that in and still use this UCA.

It would be nice if it was to get used... BTW I'm keeping the UBJs...
