Part # for Exhaust Manifold Bolts?

[miked]

Have a 1987 GN changing out the exhaust manifolds to Jet-Hot coated ones. Would like to replace the bolts/studs. Can anyone give me the part #'s. Thanks Mike D.

Bolt numbers:
upper: 25518177
lower: 25526575

The upper are not longer available. I recently had my exhaust ceramic coated and went to the hardward store and bought all new ss bolts and washers. The only oems you need are the three on the ds that are used to hold the dipstick, alternator and compressor. Just clean those up with a wire wheel. Bolt size is 3/8". Just get the right length for uppers and lowers. Or try TA performance. They sell exhaust bolt kits, but they are not the oem stud type.
