Searching for car coil packs for my 2004 LM4 5.3.
I found a set of 2001 Z28 coil packs. Should I buy them?
.
I already have two 2004 Corvette coil pack covers.
.
I have a single set of 4 Corvette coil packs from that 2004 car are round #12573190
Z28 coil packs are square, also 12558693 coil packs are square.
Question is: what coil packs will fit under my 2004 C5 Corvette LS1 coil pack covers?

As long as you get the brackets and coil harness with the coils, any of them will fit.

Ls1 or ls6 coil packs fit those covers. I just went tru that problem myself

I believe the truck coils won't fit under the Corvette covers and the covers themselves actually are retained onto the Camaro/Firebird/GTO/ Vette coils/brackets/harnesses

I have truck coilpacks with a Corvette covers installed. The covers snap onto the fuel rail and have posts on the valve covers. There may be some excepctions, but the difference in coilpack size shouldn't be an issue.
