I have a Converter from PTC which BMR offers for my TH400. I recieved my flexplate and now the bolt holes dont line up. Theres about 1/8th space. Did any of you guys file down so the holes matched up or is this a bad idea.
I took some pics with a cellphone since i dont have a camera

 

i had to file mine a little.
Stock 98 flexplate and a 5300 stall 8" converter.

 

You need a tci flexplate to make it work right. I would be scared to file the stock one and get vibrations.

 

I ran into this with my TH 350 and here is what i had to do.. I had to send my stall to TCI and they welded a new plate on the back of the converter that matched the flexplate.

Any local shop that builds converts can do the same thing.. Just a suggestion to avoid shipping
