Well, the rain moved out early and the roads dried out enough that I could get the car out. It's even better than before so I'm getting closer. If this is the best it gets, I could live with it consider how bad it was before. I do still have some adjustments to make. I need to get it back up on the cribbing so I can get an official measurement to know where I am. The biggest issue I'm facing now is the car has a shudder that runs through it as I coast down from speed. Fairly certain this is pinion angle related for sure since I don't feel it going up through speed or while driving. I'll continue to do research and see where it leads.

Thanks for all the help everyone.

If you have vibration while deceleration the pinion might be down to far. Glad you are moving in the right direction. That aluminum driveshaft will help ALOT to get every bit of vibration gone

Trey, how is this going? We’ve had a day or two without rain, so I know you’ve driven the car some.

Thanks for checking, Scott. I actually haven't touched the car. I'm also working on my friend's 69 mustang trying to get things done on it. I'll get back on the TA soon.

So I think I may have fixed the vibration today. I lifted the rear of the trans about half a degree and that seemed to do it. Not sure why as the last time I made an adjustment I had all my angles within spec when I measured without the driveshaft in place. I think the difference may be that I measured with the driveshaft in place this time and that showed that I was a little off from what I measured before. I would have though the measurements with the driveshaft removed would be more accurate since it allowed me access to the tailshaft.

Anyway, I'm going to work on closing the tunnel in now. I'll have to make a new transmission cross brace because the exhaust is almost pinned against it now. No big deal as I have to replace the floor boards too so it'll work out.

Great to hear trey!!!!

Thanks! How the hell did you see this post so fast, lol?

when did the vibrations come on?
mine has vibrations, but only above 85 on the open highway, doesn't do it on the track or auto-x (no harmonics i'm guessing)

Score!
