Hey guys. Is there a difference between the AC Delco square and round coil packs? They both say OEM replacement, but different part numbers. The square is D510C and the round is D514A. I'm thinking the round ones are the ones to get since that's what's on the car, but is there really a difference?

Here's what I found online,
ACDELCO D510C {#12611424} GM Original Equipment
MELCO-MITSUBISHI; W/SQUARE-SHAPED COILS AND MARKED 12611424
ACDELCO D514A {#12573190} GM Original Equipment
DELPHI; W/ROUND-SHAPED COILS AND MARKED 12573190; 6 speed Automatic trans.
So looks like both are OE but different shape and suppliers. I'd get round if that is what fits the mounts.
