Took the car out for a few miles on Friday despite the salt on the roads. Wanted to check a few things over and I knew I would be fully cleaning the underside this weekend anyways. Got on the throttle a few times and I am very happy with how much better the acceleration is.



Spent a good amount of time making sure my driveline angles were all good and the pinion angle also. I am happy with it. Used the Tremec app and the iphone angle finder apps because that magnetic angel-finder from home depot just wasn't precise enough for me. I wanted the transmission to point downward a little bit more and since it is not the time to build a custom dropped trans cross-member, I built some shims to put in-between the body and the cross-member out of 1/8" aluminum plate. This gave me the downward angle I was looking for, for now. . Also swapped in a 45 tooth speedometer drive gear so that the speedometer reads correctly now with the 3.91 rear ratio.





those numbers above wont make sense to you unless you use the app

these might make more sense though.. but please note, these photos were taken (and posted) not in order. this is just showing what my figured I was working with were at the time.




Hit every polyurethane and roto-joint with the clear marine grade grease. Used regular grease on all the steering components. I always underestimate how messy that clear grease gets. After everything else was done underneath I gave the underside a wipe down and got everything cleaned. Checked over many nuts and bolts, and as it sits, everything underneath the car is pretty much complete and ready to drive for the year.


















thats it for now, if anything under the car grabs your attention (good or bad), just shout it out to me. hold all comments about the exhaust, that will be next winters project.
