O-ring is a 53 X 2 I believe and the seal is a 35 X 50 X 7 - these you could do local BUT there's a gasket required also and that is substantially more difficult to come by. Here's a thread that might be a good read:

WVZR1 is correct.
On my 94, the Previous owners had +/- 3 clutch replacements due to mis-diagnosis of rear main when it was the tranny input shaft seals.
Two other things to also check.
1. if LT1 - check Oil pressure switch/fuel cut-off connection at back of intake manifold -- leak there can get to clutch.
2. Tranny vent hose -- should be at/near firewall and have a filter on it -- make sure not pinched as would cause tranny build-up of pressure which will exit easiest way --- front seals.

dont know what year your car is , theres a service bulletin #92-304-6A for 1992 5.7 engines. Flint built engines with the letter "V" as the first digit of the engine serial number have an oil leak at the camshaft plug commonly misdiagnosed as a rear main seal leak.

I thought it was rear main seal (big job), but was luckily just clutch slave cylinder
