Hey,new at this really don't know what to say

Iam doing a 88 3.9 to 5.2-5.7 mag swap I know it's pretty much a bolt in ( mounts,tran pattern,) 88 has already been retrofitted from computer/TBI to electronic ING and carb. So a aftermarket intake is on it's way.. my question is what flex plate do i use on the mag

You mention 5.2 or 5.7 Magnum, I'm assuming you intended 5.9 vs 5.7
The flexplates are specific to each engine.
