Another motor mount/crossmember question....C20

[FLYNAVY30]

Swapping an LS1 and 4L60E into my C20 Suburban. I bought the entire set up (engine, trans, flexplate, torque converter, shortened driveshaft) from a guy who abandoned a '69 Suburban swap project. My questions is, what mounts and crossmember to go with. I know lots of guys are running the dirty dingo mounts since they're adjustable, but with the shortened driveshaft, I should be able to keep everything in the factory location. I was thinking about using the CPP mounts and cross member. Any thoughts or input? Additionally, an issues using mounts that are advertised for C10s? As far as I know the motor mounts are the same between the C10 and C20.

Thanks for the help!
