I know the later model one piece rear seal uses a different part number bolt than the older 2 piece real seal for the flexplate bolts. Does anyone have the part numbers from ARP?? I sent them an email, but have not heard back yet.

Thanks

Well, Jeg's (1-800-345-4545) sell three differant ones.

7/16" x 1.00" and 7/16" x .680" and LS1 bolts at 11 mm ?

The threads are the same as old style, just the bolt head is smaller to clear the 1 piece seal. It is specific to the 87 up small block.

Just incase anybody need it; the ARP Part Number is:

ARP-200-2906.

They are a special order part, but are correct for the later model 1 piece rear seal cars.

WooHoo
