Im swapping to a RMVB TH400 in my 2001 Z, i have the spacer to bolt everything up!

Does anybody have a part # or an idea on where i can pick up some longer flexplate bolts?

Thanks!

Circle D knows the part number. Just ask them for the part number for the longer GM flexplate bolts. You can get them at the stealership they are like 8 bucks a bolt though

Cadillac CTS-V flexplate bolts #12563485. If you get them from GM Parts Direct they are about half the price the dealership will charge you.
These bolts are 29 millimeters long.

i used to have a set that came with a TCI flexplate, couldnt use them because Scatt uses American bolts in their stroker cranks-i will meas them against a stock 4L80E flywheel/spacer bolt, see if their the same
the TCI flywheel had a small spacer and thick flywheel, but not sure if it was the same as the stock FW and .400 spacer

We have not officially announced these bolts yet. But thought you guys might want to know about them. We got together with ARP and made a custom LS crank bolt for our billet flexplate. A great side benefit is they also work well with the GM spacer. You get the proper thread engagement in the crank and incredible strength with the ARP name. Let me know if you guys have any questions....

I will have them on my site soon....

They are not designed for the thinner flexplates, sorry. You can just use the regular ARP bolts. The longer bolt will bottom out before it tightens up on the steel flexplate.

My factory bolts are 28mm. Sorry, forgot to add that I was using the spacer as well. Eric L

OK, so you are using the spacer as a crank extender, with the flexplate bolted direct to the crank. Then yes, they will work. Shoot me an Ask Chris with your info and I will send you a payment link...
