Hope I can get this pic sized and loaded. It bolts to the crank flange and the dial indicator clamps in the slit.

I was dreading cutting the trans tunnel frame and this is all I was comfortable cutting out to this point with an opening about 5 1/2".The only way I know to cut the flat lip is with a saw blade without the frame to hold it.

I flattened the lip with a 2lb hammer just fine

The lip doesnt need flattening
You need to cut vertically on the tunnel brace

Dialing in the bell with offset dowels can be exhausting if you never did it.I got within .020 with .000 on 1 side to start.I will try again tomorrow.
I had to remove the bolts holding the bell to the engine on the lowest 2 boltsto allow the dowels to move the bell a couple of times and check other bolts.

Are you moving the offset dowels towards the crankshaft to help move remove the run out?

If those numbers are correct the hole isnt round.
Take readings at 12, 3,6 and ,9. Ignore the rest

What he is seeing is very common, it depends on where you locate the zero on the dial indictor to start with
I now start with the zero at 12 o clock and go from there up
If it is oblong, goes to +.012 and then returns to zero and then goes to -.017 and then returns to zero at 12 o clock I know where and what size offset bushing to start with shruggy
It ain't easy but it is doable up wrench grin
