Is a taab 7505a bellhousing the same as the taab 7505 bellhousing listed on Mummert's site? I didn't know if the 'a' at the end means anything.

I picked up a taab 7505a bellhousing at a swap meet today and I'm hoping to have it modified for a t5. I think it is a 3 speed truck bellhousing. Just want to make sure that it will work.

Thanks for any input.
