where are the mc-1 y pipe seals?

[henleyhale]

I have an older mc 1 on a ford 5.0. Runs reals nice when I had it in last, just replaced the floor, stringers, gas tank, and foam, on the 77 sea ray sun runner cuddy. Now for the hardest part of the project, I cannot find the three o rings to put my y pipe back on, does anyone know where to get them?

awesome! Thank you, Im still unable to find the two smaller orings below it. the larger one you gave parts for, I may have called the drive wrong it is infact an 888. thanks for your help.

The engine is an 888 (Ford 302. 8 cylinder, 188hp), the drive is an MC-1... The decal on the drive that says '888' is the engine designator. The same drive is used with many different engines, the decal is the way 'outsiders' can tell what engine is hiding in front. The number for your small 'O' rings is 25-23145...

Thanks chris guess i had it wrong all along my decal says 228, none the less thays the right o rings you guys rock

'228' is a GM 305 (5 litre), 228hp. What engine do you have? Drives are completely interchangeable. Fords have the distributor at the front, GMs have is at the back....
