I've used both the Mopar electronic - recurved - and most recently an FBO, all with MSD boxes. Real happy with the FBO, more expensive than "rolling my own" but it was drop in, set initial & check total, & go. Either way, their plate is brilliant!
FWIW, WestTech (the MSD repair guys) tipped me on using the '90-'91 Ford F150 302 epoxy coils, great & inexpensive auto-parts-store upgrade.
