Murray,
Your mention of raising the front of the diff made a few more brain cells work and I remembered how I did get the required diff angle.
On the cradle bushes, I cut the steel tubing through the bush level with both sides of the cradle arms. The large washers I made did two things, 1, they clamped the cradle to chassis which reduced the effect of the rubber bushes to almost nothing and 2, I could use this large washer as a shim.
On the diff I replaced the rubber bushes in the front of it with a round piece of steel that was flush with both sides of the flange. Again I used large fabricated washers underneath of the flange to bolt the diff. The top of the flange bolted flush to the cradle. With the new position the diff I just fine tuned with with different thickness fabricated washers under the rear cradle bolts.
The diff rubbers were replaced on a recomendation of the company that did tailshaft. They said they have seen these rubbers ripped out on acceleration with high horsepower cars. As you are using a chev motor that might not be an issue.
The secondary side effect was I could change the diff angle.
