[69gmcc10]

you have several options, bu my favorite is dirty dingo. They have the DD mounts with multiple bolt holes locations to put the engine right where you want and use the original perches for about $60, exhaust options might be limited. Or you can go to 73 and later perches and get the dirty dingo mounts for that vintage and have infinite adjustability for and aft with more room around the headers for a more header options for about $105.

there are other good options that can meet your needs, but those are my recommendations.

cant help ya on the cpp stands
