    My stock engine is long gone ('91 c1500). And I need to know what pieces I need to take the motor mount adapter plates, to the motor mounts on the frame. Is it just a small steel piece or what? I guess it would be the motor side of the motor mount setup.

    oh, and is anyone other than S&P making the motor adapter plates?

    thanks

    Search Ebay. There's a guy on there that manufactures them. They bolt to the engine, not the frame. You re-use the original factory 91 c1500 mounts with the adapters.

    I know the adapter bolts to the block. I need the part that bolts to the adapter, I can&#39;t find a listing on GM parts pages, and haven&#39;t seen any aftermarket.

    Are you talking about the factory engine mount cups that bolt to the stock block? Salvage yards sell them. I got a pair for &#036;10 when I converted from my V6 to V8.

    Yes, I just want to make sure that that piece is all that I needed. There are no spacers or anything with them on the block. Are they just solid pieces of steel? Or do they have a rubber/ poly insert also?

    No rubber or anything, just a steel cup that has three bolt holes to mount to the engine block and a long bolt that goes through it and the rubber engine mounts that should be bolted to the frame crossmember. If at a salvage yard, try to get all the nuts and bolts when they pull the mounts. The main bolt is about 5" long and should have a nut to come with it.

    Was your truck a V6 or V8?

    Ok, It sounds like I know what I need. I went and ordered the V8 engine side mounts online. Frame was a V6 frame, but I have the V8 mounts off the original truck, w/ new poly inserts, bolted on. Just need to get some new bolts and I should be all set then. It was hard to tell exactly what I needed to get w/ the diagram they had online.
