I did my 4L80 conversion and am having a hard time getting pinion and driveline angle correct and part of me thinks the stock 4L80 mount i have might be too tall... The picture below is the one i have in the car. Does anyone know the difference in size between them and the 4L60 mount and will the 4L60 mount bolt up to an '06 4L80 tailshaft housing? ~Cole~

When I did mine the part number was the same for the 60 and the 80. I'm using my old stock rubber 60 one.

I did some investigating yesterday on this. I was right the 4L80 one i had was about 3/4" taller than the energy suspension/poly mount and 1" taller than a stock 60E mount. I swapped in a E.S. mount yesterday and it dropped the front 2*
