Yep... been there, done that. Got the GM alum thingys and the GM mounts.
To give you some idea, The bolt protruding from the top and the bottom of the GM rubber engine mount hits the very center of the chassis side rail, That chassis rail is a 4" section. Whereas in the pic posted by Boxhead that bolt is inside the chassis rail.
Further the center of the diff pinion is in a line 1" above the bottom plane of that chassis rail and is horizontal ... that is 0 degrees.

So as in the pics in Baz's gallery the base of the rubber mount shown in Boxheads pictures as being level with the top of the chassis rail has to be level with the bottom surface of the RMC chassis rail.
Real bugga really

Here is the pic from Baz's gallery. As you can see Neil cut the inner rail and boxed to the side rail and a flat plate at the base on which the rubber mount sits.
That is major surgery to me. Much better to leave the inner chassis rail. Toss the alum GM mounts and make new compact steel ones and use a urethane mount not unlike those shown earlier.

And here is a cut and shortened GM mount in my chassis in an attempt to get the mount bolts inside the inner side rail. Achieved the narrowing but was still too high in the chassis.
Problem was ... tailshaft to diff pinion alignment ....was still 40mm too high above the side rail.
That lil pink vehicle in background belongs to #1 grand daughter.  )

See that lil pink and yellow thing in the background. I'll bet my grand daughter driving that will beat your cobra to ermmmm 5 mtrs distance and not even raise a sweat.
Cheeky bugga
