[V8] Experienced? I Need to Know, "Older" Parts in "Newer" Models

[bw at UDel.Edu]

Hi,  My '92 V8 has a right distributor with a loose Hall Sender that causes problems 
because it lost its glue bond to the casing. I bought a pair from a '90 and found the 
length of the engaging shaft is slightly shorter, so it won't lock-in to the cam.
   Can I switch the ends (unlikely) or try to glue the sender back on the '92 unit? 
Does anyone want to trade your '92 or '93 for my nice '90 distributor? (Or just buy 
my two '90 distributors)
   My car runs fine until I floor it, or shift down manually to second, then it backfires 
once and looses its timing resulting in stalling. That goes away after sitting for 5-
10 minutes, maybe the computer resets itself. It restarts and it's back to "normal?".
   Does anyone have experience using '90 engine or transmission computers in later 
model '92-'93 V8s or any of the above?  Thanks,  Bob
