4x4 engine perch angles?

[havi]

Can someone put an angle finder on their engine perches? I'm trying to find two angles and a measurement:

#1: the surface the mount bolts to is 45 degrees facing each other?

#2: the angle is leaning back about 4.5 degrees, or is the perch level with the frame (not where it bolts over the top of the frame, but on the engine mount end), and is the frame level, or lean forward 4.5 degrees?

#3: the center of the perch-to-mount holes is 16" or ?

I had all of this at one time when I did the 300 swap in my '79 Bronco, but I lost it. On top of that, I kept the 400 4x4 perches from it, and I can't find them either. This CRS syndrome is really getting on my nerves.

Yeah CRS is the pits. I can't find the lid (with forks) to an extra T18 I got! :/

I'd be the guy for angle job -if- you're planning to go with a 300i6 because
I've got a 360FE and they're supposed to be the same perches of all weird
things. Guessing the 351m/400 perches fit a 429/460?
