I'm using a GM 4L65E transmission in my build, which is going well btw...anyway, in the kit are 2 size spacers. Part 33238 are 1.09" spacers in the trans mount parts. Part 34674 are 1.25" spacers in the GM trans mount adapter parts.
Assuming the adapter spacers but, want to be sure of course.

Thank you once again in advance,
JW
