I’m currently looking into some advice on where to go to rebuild my 5spd transmission.
I have three currently.
(Can be in any of these states MD, OH, NJ, PA, DE, WV, VA)

One is currently in my car and it has been through a lot. Cracked corner and 3rd is a tad chunky. A hand full of people learned on her + never has been rebuilt.
In regards to the others one is an ALH the other is a BEW. I’ve been told that the only thing that is different is the bell housing in them.

I’m just trying to find a reputable mechanic that can rebuild my spare and put in a bigger 5th gear. Or even better discuss options to potentially actually getting a 6th gear.

I hope you can find somebody good and reasonably priced because one day I would love to add a Wave trac and a 6th speed !

Bellhousing is identical in the BEW and ALH. Both 02J. Slightly different gearing on the BEW, but just barely. There are also 2 different versions of the BEW trans - early and late (split is late 04). Different differentials installed in the newer ones. The ARP ring gear bolts fit everything up to the early BEWs - not the later (even though most applications list through 06).

Shipping them out to @Matt-98AHU might be an option? He's also been building 6sp from newer more readily available units.
