I'd like to know also had a 4l60e trans bell housing that the dowel pins were too big, I thought ls and earlier housings were interchangeable??

I'm pretty sure they are the same. I know that many times corrosion can cause this phenom. I may be wrong but I have used early 4l60 from a sbc on a ls motor with the crank spacer

LS motors use the same pins as first gen SBC. I had to use offset dowel pins to align my bell. Just bought off the shelf Moroso units.

The pins are in a through hole. You can get a punch on them from the engine side to pop them out. At least they were on my aluminum LS2 block. Don't know if the iron blocks are different
