Thanks! it does have the tapered seat plugs.
What's getting me weirded out is with the engine mounts, I bought a set of mounts off a later 250 to mount it in my 81 Monte.
The mounts are flat on the side the bolts to the engine, but on the drivers side the block has the top mount ear recessed more then the bottom two. I don't know if there was a difference in engine brackets or casting of the mounting bosses between years.
Any ideas on this?
Thanks again for digging up the info to confirm what I have here!
