Easy (I hope) 200R4 Questions

[70L34]

I converted a car from a T400 to a 200R4 and need a flexplate cover. Anyone have a source or a GM part number?

Also, one of the tailshaft trans mount holes stripped while I was torquing it down (no more than 35 lb-ft). Can I just heli-coil this?

Thanks in advance!

I bought a GM 14073768 cover for my 200-4r. Application was
for a 1986 Monte Carlo. A Heli-coil should work, or you could
thread it to a larger size.
