Does anyone know the GM part number for flex plate bolts or the ARP quivalent number. The dealership ordered me the wrong ones and swear thats the only part number shown. ARP does not have a seperate part number just for the LT1s. None of the performance parts website have flex plate bolts listed, just flywheel bolts

Aren't they the same thing?

No they are not. The flywheel ones are longer. ARP sells them ONLY in the Pro series. The ones you need will be for the 1 piece rear main ones. 200-2906

I've used the ARP 12-point flex plate bolts and didn't like them. The head on the ARPs is so large you can't get fit a socket between the rear hub and bolt heads. So, I bought replacement OEM bolts at the Chevy parts department. They didn't have any problem looking-up the part number.

Also, make sure you don't have a powder coated TCI flexplate and use some thread locker along with the proper torque.

Yeah I ran into that problem when I was putting mine back together, if you have the car on a lift or the motor out it was pretty easy for me just to slightly tilt the socket and get everything properly torqued.

I ran into the same problem. Not a big deal though... I used an old socket and ground down the one side untill it fit between the head of the bolt and the crank. You only really need to put the socket on there to torque it.

Also I took the powder coat off the flexplate where the bolt heads were with a diegrinder and a 3M rolock disc... You should always do that on a flexplate.

The Engineer

You should also use the diegrinder to sand the powder coating off the area where the crank hub mounts to the flexplate (back side). Also, I think TCI has now quit powder coating their flexplates. But check to be sure.
