62 C10 283/TH350 ANGLE for X-MBR

[robber grin]

I'm at the point where I need to get the 62 C10's chassis ready for the V8 / automatic swap.

I had sort of planned on bolting the 283 up with a 3 speed bell housing and setting everything up based on the bell mounts - to mark the frame for side motor mount stands (with 1" spacers), as well as set angle on driveline for transmission crossmember that I will be making for the TH350 shortshaft that's going in.

Understanding the factory standard bell mount crossmember has to go for the new set up, I figured this would be the "easiest" way to document correct driveline placement and angle before the removal of the factory crossmember.

Then fabricate a suitable automatic transmission cross member working off the 3 factory punched "cresent" array of holes in the frame, and retain the factory angle for motor and transmission.

I only want to do this once and hope to get it right.

Anything I missed? Suggestions? Advice welcomed!
