Ok she’s all together. I ended up with:
New A&A iron front drum.082 front clutch clearance, 5 red clutches flat snap ring
Front clutch case channel restricted with a drilled dorman plug like the beat trans case got with the tf2 kit
Re-used forward clutch drum from old trans- red clutches & kolene steels still look great.
Re-used kevlar bands still like new after 100 miles.
A&A billet rear servo, tf2 blocker; 2 turns out
A&A front servo link bar, 4.2 lever, controlled load defeated w set screw 1.25 turns out
.040 endplay- higher than I was shooting for but well within specs per Munroe book
Servos and clutches all air check good
Accumulator retains spring between piston and valve body as per John Kunkel over and over in a hundred threads on the search function. It shifts plenty hard already with decent throttle application.
Double checked that the deep pan pickup extension was clocked properly 😉

It will be interesting to see if I can feel the difference with the controlled load blocked in the kickdown piston and the 4.2 lever.
