Well, I had decided against it, but damned if I didn't find a bubble-back at a swap-meet for $15 including the filler blocks.

So . . . a couple questions.

1) I've been reading where the filler blocks don't make that much difference. Should I bother with them or no? If I do, I can't find the fastener part# on the diagram for them. Any idea what size & length, or even a part #? Seems like at the very least the fillers support the gasket a little better.

2) I know which piece of the block needs to be cut out. Question is how far back do you cut it and how much length do you take out?


Thanks all.
