Are these interchangeable? A lt1 plus t56 out of a 95 firebird just popped up on Craigslist for a grand. If the trans is the same this would be a great start to my Miata swap

I think I've heard that the early T56 has some deficiencies compared to the later ones, but for under a grand it's probably worth it if it's not in need of a rebuild.
EDIT: The swap is apparently more complicated than I thought based on how google returns endless results of "get the front half of an LS trans and bolt it on". Something to do with the LT1 153 tooth only bell not clearing the LSx flywheels that are all the larger "168 tooth" diameter. So you need the bell, front plate, and input shaft for a LSx T56 since making the flywheel on a LSx smaller is much more expensive.
It says the trans was rebuilt 2 years ago but the engine is having issues
I thought the LT1 trans was rotated in comparison to the LS1 version? Going off a hazy memory, so correct me if I'm wrong.
I'm pretty sure Hot Rod or Car Craft has done a part-by-part list of exactly what's needed.
BrokenYugo is correct. LS1 specific bellhousing, front cover, and input shaft + shims. Don't forget the hydraulic throwout bearing!
I think Rockland Standard Gear still sells a kit that would get you almost the there for just under 5 bills. You will have to get a bellhousing and clutch hydraulics. The Gear Box and D&D also have individual parts.
buy it and ebay it for $1500, use money to buy an ls1 t56
If I'm not mistaken, the LT1 T-56 fits traditional small blocks. Use that as an advantage. Follow Patgizz's advice
Just confirming: LT1 and LS1 T56 are different, particularly on the input side. There are clutch kits to allow the swap, but they're pricey. Easy button is sell the LT1 trans and buy an LS unit.
Converting isn't cost-effective unless you do the work yourself. T56s assemble from the front - back, so you can't just pull an input shaft and swap it. You take the case off the front plate and work down to the input from the back.
Since you said it is having problems, that might be required anyway. If that's the case (pun intended) just have the parts on standby and re-assemble with LS front bits. The way I would do it is to have an LS front plate and input shaft and just re-assemble on the new plate. There shouldn't be any additional labor involved, just a few hundred bucks in extra parts.
You'll likely need 2nd and 5th synchros anyway.
