Default Which trans mount?

So I am swapping a 99 trans am ls1 auto into a 95 z28.

I noticed that the trans mount from the 99 is broken so I went to autozone to buy a new one.

The one for the 99 was $74 and the one for a 95 Camaro was $13.

I ended up buying the lt1 trans mount.

Will this still fit perfectly even though it looks different from the ls1 trans mount? Or should I just pay the $70 for the ls1 mount?

The part number was 2817 for the lt1 mount.

Not sure on your specific issue, but I can tell you NAPA had the correct part number for my 2000 and it was less than $20.

So the one from NAPA looks like this:



And the 99 Trans Am one looks like this from Autozone:



And the LT1 Auto version I bought from autozone looks like this:



Autozone has two 6 speed versions with one looking like the NAPA one.

And by looking up the 99 Trans am through NAPA I get the same ls1 version that autozone has but for $82.

Now I am really confused lol. I would think that the LT1 version would work, since I believe all 4L60E's have the same dimensions, etc.

I suspect you are overthinking this - any of those will work.
IIRC I am currently using a TH400 mount spec'd to a 1970 Big Block.
