what size are the bolts typically used? Mine uses 10mm x 1.5, are yours the same?

Mine required the M10 X 1.5's also. Same as the GM OEM M10 X 1.5's but shorter because of the blind holes in the PI lugs. It was shipped with little M8s though??

Same I used for mine. Although my verrter didnt come with bolts. I got new stockers. I had to grind a bit of the unthreaded portion from the end of the bolts. Blind holes didnt allow them to protrude at all.

thanks guys, what length did you all go with? 20mm?

Depends if you can find flange head bolts like OEM or need a washer. 20mm will be too long. That's all I could find and I had to cut them down. PI's instructions say 12mm- http://www.converter.com/book_flywheel.htm But I see that the instructions regarding the TC to flexplate clearance still say 1/16"-1/8" for all apps so who knows? It would be easy to determine now with the TC off. Screw a bolt in to the TC until it bottoms, then back it off a little. Measure how much thread was buried and add the thickness of the flexplate plus washer(if any). I can't recall exactly what I ended up with but I think it could be a little longer than 12 mm.

I did that earlier today, about 2/3'rds of the bolt or 6 threads before it seated. Don't know how thick the flexplate is, so I'll have to wait on that I suppose.

Allow about 3mm for the OEM plate.

Just a note, if you go with a TCI flexplate, you will need longer bolts due to the increased thickness of the TCI unit.

Cleaning up today and I found these on the workbench. Maybe PI did send me the right bolts and I got them mixed up with another pack of 3 black 8.8 bolts. Don't ask me where the smaller ones came from?? They are definitely M10 X 1.5 X 12mm. Add the extra thickness of any aftermarket flexplate to this for your bolt length.
