Both cases are apart...

I've got Tate's enourmous tranny over here to measure the 31 spline shaft...


First an adapter plate has to be made to bolt the 241 to the 205. This should be easy enough. Bring both cases up to the machine shop and use the digital readout on the mill to get the bolt hole patterns and to ensure the input and outputs are concentric.

Next I need to respline and cut the 241 shaft. I plan to leave it full length and turn the part I need to spline to the right OD, then I'll cut it to lenght. My thought behind this is it's already center drilled so it "should" be concentric in the lathe.

The only glitch I didn't forsee until tonight is one of the 205 range shifters will hit the 241 case. Regular doublers solve this buy moving the 203 box out ~2 inches from what I can see. However, there is nothing but empty space in this part of the 241. From my 5 minutes of looking at it tonight I think I'm just going to cut this part of the case out and tig weld in a concaved piece of aluminum.



So thats the doubler part... then I get to do it all over again between the tranny and the 241. There are stock adapters to do this, however they are around 8"s from what I remember. I have one in the blazer and I really don't want that long ass setup. My entire doubler setup should be the same length as whats in the blazer.

So my plan is to take a 2wd SM465 and then machine it from 35 splines to 27 splines. Then make another adapter...


P.S. Anyone have a parts washer I can borrow? I'm going to but one as soon as they go on sale at harbor freight. Maybe I'll take the 205 **** up to the car wash and blast it, the inside is kinda gunky...
