Excellent! I am taking it out today for its maiden break in of the gears, will just be cruising, no loads at all, so i hope to feel no vibrations! What kind of improvements Do U think I will see in my 60's over the 3.42 gears? I am hoping to see .2-.4 at least with the 3.89 gears. I do still have th...

Thanks! Did I DO IT RIGHT?

Well After I took the car off the stands in back under rear I have 3 degrees pinion angle. My driveshaft coming into pinion is at 3 degrees, and my pinion is at 0 degrees. Hard to see in pics , took with my phone.Can't go anymore as there is no adjustment left in upper arms.. My new driveshaft is ve...

Thought I would update this thread as i am completed with it . The cell is sitting on some 2x6 aluminum tubes bolted thru those and the trunk, and the straps are attached to the tubes with 3/8 bolts going thru them and spacers inside to not crush the tube, I plumbed up the twin electrics just in cas...

Yea That was my thought ,but the more i look at things etc, your right the driveshaft will be angling down more to set at the rear. I wasn't thinking straight ,lol. I decided to just do the 3.5 and be done with it, According the mark williams site with a driveshaft of 58 ctc the critical speed is st...

I looked at that pic, and that is where I get confused, whats the difference of taking the angle off the back of the seal flange on trans and off the flat of the yoke in back Then taking it off the diriveshaft? If the trans is at -4 isn't the driveshaft also going to be that coming into the yoke? I ...

Ok sounds good!.But I guess I don't understand why I would need the shaft if I already know the trans angle of -4? that isn't going to change when i slide the shaft in. I am calling the guy tomorrow with the measurments for the shaft, I took it from the seal to that front of the yoke 62 3/8, he said...

I am setting it up for street /strip Its my car in my sig. So If I understand you correctly Being that my trans /engine is -4 degrees taken at the back of the trans seal with angle finder, I would then set my Pinion yoke to 0 +1, thinking my Pinion will rotate 3 degrees up under power to match my -4...

So I need to get the drivshaft built first? According to this site i don't measure with the driveshaft in? This is all new to me so trying to figure out the correct method to set it up. I am using UMI ultimate upper arms, UMI boxed lower's with their poly bushings in, and just plain old new rubber o...

Getting closer to getting the car movable again, Now last year when i checked the pinion angle with other rearend with the Constant Velocity driveshaft and street tires it was about -2,-3 On the very back joint I think? I never checked with my Slicks, and We know it went 1.63... Ok Now this year got...

Would take 200 shipped.. this is the only pic i have when i pulled the cover too see what broke. I also have another posi with a ring gear attached that looks to be new or in very good condition, I would let that assembly go for $350
