Well, I went out and tried to put the two together today. Found a couple of problems. The shafts fit perfectly but, the long snout on the 205 bottoms out 1.5 inches before they meet. 2nd problem, with the factory tailhousing, the inner shift rail lines up perfectly with the side of the housing. Didn't think to snap a pic but, will post one tomorrow. (gotta work tonight).
The clutch set up is the factory hydraulic set up. I know, right hand slave may cause driveshaft interference. Being the wide ratio shouldn't be a problem as I've got a 454 for power and gonna build another higher hp/tq output motor soon.
The twinstick idea would be somewhere down the road as this is my DD.
I've got the bench seat also but, down the road may be buckets if I can find a decent donor vehicle.
Stay tuned guys and gals, more to come...
