Happy holidays everybody!

FINALLY got my '93 'vert back (long story), so good to have it back on the road!

I'm curious about cluster hood variations. I see numerous hoods on eBay, but after pulling one a couple years back I discovered there are at least two different designs, one with L-tabs and one with locking push tabs and they are not interchangeable. Anyone know what model years got which design, or was this a variation between the NA and TT?

Are there any other versions?

Thanks all!
