Larry,

Looks like we're neighbors. I'm not far from Great America.

AFAIK, all 450SEs are 116.032 whether US-spec or otherwise. A 116.029 is a 350SEL. Wonderful car but not officially sold in the US.

For parts, click on the FastLane or PartsShop links at the top of this page. Phil will sort it out for you. But I'd be comfortable ordering mounts for a US-spec 73 450SE.
