1991 ZR1 torx bolt size
 
Two bolts stripped out on intake manifold. Took it off to replace spark plug wires. Got the bolts out but need to know the size and any place that sells these.

Thanks, kind of pricey but what are you going to do? Had to buy a set of original spark plug wires awhile ago. Of course they don't make the correct ones anymore.Found a correct set. $175.00.

Jerry sells the wires for around 80 bucks

You need upper plenum bolts? M8x1.25-25 for those. Jerry should have plenum bolts in both new and used. Jerry uses I believe 11516081 and 11516081-U

Q: Were the wires roll-stamped with "LT6" in white along the lengths?

No,LT5 along with the cylinder numbers.

Did you replace these already? If not, PM me. I do have some original bolts (I replaced mine when I refinished the LT5)
