OK this is it. I am done with it. I found a list of
standard aluminum extrusions and 3 X 1.5 X 1/8 channel 
is available. This mount can be made with nothing more than 
a hacksaw and a file. You need to be able to heli-arc weld 
of course or get it done. No need for an CNC mill.

The weight of the channel is a bit much at about 3 pounds for
a 36 inch long piece but a bunch of holes in it are not 
going to hurt as it is overkill for the job. Each hole
2.5 inch diameter hole in the web  will remove 0.06 pound :-) 

The channel is merely bolted to the bottom of the engine 
near the bell housing end with the pan bolts. 
Fits all years. 
 
1/2 inch square .049 4130 tubing could be substituted
for the 5/16 round. It is a wee bit easier to align
things when welding.
