Well, I do appreciate you listing some alternatives. I am familiar with everything you mentioned as I have followed the OD tranny market for at least a few years, throughout the development of Keisler's latest offering. Fitment-wise they may be slightly better, although cost wise I don't think they will come anywhere close to what the MA5 can currently offer. A little extra fabrication with an overall significantly lower cost is an acceptable compromise for me. Unless something were to "rear its ugly head" and make the swap implausible, I don't know if I see myself pursuing anything otherwise.
Right now it's looking like...
MA5 Transmission
3.9L Dakota Bellhousing and clutch fork
AX15 Bearing Retainer
11"/143-tooth 5.7 hemi flywheel(drilled for 10.5" clutch)
Jeep slave cylinder with advance adapters hose kit
Undetermined clutch master with Dakota angle adapter(not sure year?)
GM 26-Spline 1.125" clutch and pressure plate
Custom pilot bearing
I think that's bout it for now.
