I'm running a 70 Skylark with a crate sbC350/T-10 manual. I shop for a 70 Chevelle when looking for parts like headers, pulleys etc...hey it's a chevy. I also used 69 Chevelle frame pads and mounts that just bolt on and move the motor mounts forward. T-10 has the same length as a turbo350 so it landed on the trans mount with no mods to the driveshaft. Skylarks and Chevelles are physically the same under the skin. Easy conversion once I realized that.
