Flexplate
Hey everyone, haven't been on for a long time due to my truck being down since December and not having the funds to get her going again. Well i finally got her in the shop and the tranny out to replace the flexplate. Back in december my starter sheared the teeth off the flexplate. Now its time to find the fp and i'm wondering if it'd be the same as a 1990 C6 trans. Napa, oreilly's, autozone, etc. show N/A on the 1991 E4OD trans. But i can get one for a 1990 C6 for around $55! Thanks for the help guys!

Ok, i found that the flexplate i was inquiring about is going to be the correct one, the only issue is it's not balanced, it doesnt come that way. Some of the flexplates for this motor/trans are balanced, some arent...am i going to run into issues with that and should it be balanced? Thanks guys!

The 6.9 and 7.3 IDI's are internally balanced and the flywheels/flexplates are neutrally (Zero) balanced.
Thus intermixing them is not an issue and is done all the time!
