To the OBS guys out there, did you use your factory 4l60e trans when you converted to the LS motor and a flexplate spacer? I'm swapping a 5.3 into an 87 2wd Suburban. I have a 4l60e trans available to me from a 99 Suburban and I was wondering if I could get this flexplate to make it work. LS Series Flexplate 12621399 - Crate Engine Depot GM #12621399
