well i have another issue not related to the impact or engine noise..

along the way in this build i overlooked something very important...and when i say overlooked, i was aware of it, i just kept it on the back burner....well it bit me...

i have a bad trans/driveshaft/pinion alignment problem...and there isnt much i can do about it easily.

the transmission ended up a little lower in the car than it was, and possibly at a different angle(i dont have another 7 around to measure), also...im not sure my grannies 8.8 is at the right pinion angle to start with...ill verify that when i can pin down the info i need to do so....

this results in the pinion being about 4 deg north of the trans angle, and almost directly in line with it......it caused an immediate failure of the yoke Ujoint within the 140miles i put on it so i put it on stands to investigate the vibration and discovered my oversight....but an oversight i couldnt really avoid...due to space constraints

SO i needed to change the rear end gears anyway, so it needs to come out now to investigate further my problem....and time is running out for DGRR...and money ran out a long time ago...

im probably going to have to build a 2 piece driveshaft or something...i cant really move anything around in any direction...
