On a side note you should keep an eye on the tubular k member and you are going to want to weld the lower control arm brackets to the rear end. If you guys switch to 315 Hooisers those will move or break most likely.

If they do work themselves loose over time- even while held with a set srew, can a wicking grade Loctite like their '290' be used on the set screw & the plate driven in with the spanner wrench to prevent them from loosening? - just my thought

So I'm thinking about the LCA's with the roto joints for their benefits next but how often to they really need to be re-tightened or is them being 'loose' just a function of them not being torqued down during manufacturing and the end user is to sinch them down?

The Roto-Joints have set screw on them so they won't work loose. The are a wear item though, depending on use the Delrin inside can wear. In this case you remove the set screw, turn the retaining ring to the next click and reinstall the set screw. Wear will depend on how much use. We are running them on all 8 rear locations on our '79 Monte Carlo that gets street miles and has been doing quite a few auto-x events the past year. We have yet to need to adjust the Roto-joints yet. We also have many other cars using them.
I hope that helps,

Ive only had to readjust them once so far and they still are silent. I just recently did an auto-x event as well, so the are taking abuse.

Here are a few pictures from the Syracuse Nationals autox two weeks ago.
The car ran the 4th fastest time out of 70 cars and we also placed 4th in the shoot out. The clutch was slipping really bad towards the end and that is our next project.

And a little cone damage...nothing rubbing alcohol didn't fix.

Looks like you guys are doing well.
Get a clutch in it & come on down to www.scca-susq.com/ Aug 31st. Next event is a double at Harrisburg Farm Show. I'd love to see how you compare to the 2nd & 4th gen regulars there.

Pulled the transmission and not much left to the clutch. We don't know what abuse or miles it had on it from the previous owner.
New clutch is going in the car this week, we are just waiting for it to come in, twin disc with aluminum flywheel. We are headed to Pittsburgh International Race Complex this weekend for the Ohio Muscle Car Challenge.
Quick alignment check as well. We are able to get a lot of positive caster with the UMI front end. 7-8 degrees positive feels very nice and working well.

What alignment tool is that, and how do you guys like it? Been looking at some options lately because I would rather do it at home. Would make it so much easier to change set-ups for different tracks.

It's a Specialty Products FasTrax. Works nicely. We have a Longacre for steel hubs but the face mounted wheel works best with the exterior clamp style.
