I'm going to order a yank ss 4000 stall friday after work! I was told that I could just use my stock flexplate. Was told the 98 and 99's were better then 00 and 01's. The car only has 50,000 miles on it. I was looking at the TCI flexplates. Any thoughts on this?

I replaced my fp with an ls3 fp during my tc install. I had the 01 shity fp though. It was cracking on the teeth above every tc bolt hole. I cant say how strong the 99s are but I do know they are stronger. I would just replace it anyway. Do a search and see what a broken fp can do. Its scary as hell man.

I went through this same dilemma about a month ago. I have a '98 which supposedly has the stronger flexplate. I went ahead and replaced it anyway. It's cheap insurance when you think about it, and you might as well do it while you have the trans out anyway. I was only doing a 3200 stall, and I see you are getting a 4000, which makes me think the stock flexplate will be under even more stress with that converter... JMO, but do what you gotta do.
