I think this is my next project car

Please reply to the second part of reply #100. Do you intend to reposition the engine trans?
 
I just found out the angle meter the slope indicator changes if you have the meter upside down. So yes the trans is down in the back 3.4 deg

Shaft is -1 deg down toward the back.

And the pinon is falling down towards the front -2, deg.

Oddly enough the slope indicator on the pinion read the same upside down or right side up. Not sure why.

I'm very confident in these measurements. I verified them (roughly) with the dial angle indicator

Sorry, the responses are coming so quickly I'm missing some of them, and missed a question or two.

Yes the 9" is in.

I have the engine trans set to the -3.4 falling down to the back and will install the cross member to keep it there.
The 2" drop cross member came in today.

I've found 6 degree shims for the axle. Looks like I may need a 5 or 6 degree shim. As I said every damn time I check this with the angle meter it changes some. Car isn't moving, and I believe I have the meter held tightly again the part I'm checking. Frustrating.

I seriously doubt 1 degree is going to be a major issue... I would probably buy the 5 degree shims, install them, and see where the numbers are.

Yes 5 degree sounds good, but finding them. Lots of 4 and 6 degree but very few 5 degree with shipping that isn't $72 for a $20 set of shims.

I'll do some more looking tomorrow.

I may go with a 4 degree shim. Or is it better to go with a 6, or a 4 if I can't find a 5?

I've been thinking how to hold a piece of material to mill a 5 degree shim and have one end of it thin. Haven't come up with an answer to that yet.

Between a 4 degree and 6 degree, I would opt for the 6... with the numbers you have.

If I was going to mill a set... I would get some suitable material and tack weld it to a wider piece... clamp the edges of the wider piece to a sine plate and set on the angle. Mill the angle, then drill the center hole... finally cut the tacks and dress the remaining weld.

@alloy,

I'm concerned that because of the very shallow current drive shaft angle, when you pitch the pinion shaft up, you may find that the pinion shaft is higher than the trans yoke. I'm almost certain that it will be.

What would prevent you from raising the back of the transmission? Could you raise the trans tail shaft to get zero degrees incline on the trans?
That way you will only have to put a 2.2° shim on the rear end and you will get a closer to 3° drive shaft angle
