question for you tcase gurus. I have these 2 cases and am wanting to make duals. they are different cases but both 21 spline. is it possible to use them with the MC-07 adapter? 
just wasnt sure because the case in the top pic has the rails coming out. forward shift?.
the one with the rails is forward shift, you can use that one as the crawl box and bolt the top shift behind it. or go to pick a part and get the shift rails from a topshift to convert your forward shift. and both would be topshift
