    I have this on my ‘00 LQ4 without the spacer so that it fits with the TH350 and everything is lining up but it looks like the starter is not going to be able to engage. Do I need to get a different starter?

    Asked by: FBODY96
    Depending on your application you may need this flexplate for proper starter engagement - https://www.jegs.com/p/JEGS/JEGS-Jr-Dragster-EV-Conversion/3740786/10002/-1

    I am hooking up a 700r4 transmission to 5.7L LS1. Will this flexplate work? If yes, as is or will I have to elongate converter holes? thx

    Asked by: kh700
    Yes, this will work for your application. You should not need to elongate any holes when using this, check your torque converter bolt circle to make sure it will fit this flexplate.

    I have a 98 Trans Am swapping 00’ LQ4 6.0 to stock 98’4L60E will this work?... 

    Asked by: Blkxtreme
    You will need to check as some 6.0L engines use a flat flexplate. See the footnote on this item.

    I'm trying to bolt a 1998 non ls 460e trans to a 1999 5.3 Silverado cause I screwed up bought the wrong used trans would this fix my problem due to the removable bellhousings on these trans are different lengths Wich convert/belhousing would I use

    Asked by: Oldkentucky
    correct that would fix the issue you are having with the bell, but you need to also use a normal SBC torque converter too.
