Replacing Manual Trans for TH350 Automatic

[iehotrod]

Hi Folks, I need Help from the seansoned C10 builders.

I bought a 63 c10 long bed with a 6 inline motor and no trans. They have removed the 3spd. cross member and the clutch pedal. Also they intalled an nice chrome steering colunm for an automatic.

So I have purchased a th350 installed it and used a 72 c10 crossmember. It appears the E-brake crossmember and cables will have to be removed in order to us my 72 C10 trans crossmember or any crossmember period.

I have a short 2 piece drive shaft but yoke only goes in about 2 inches. So I took the off a 72 c10 long bed drive shaft and it is two long maybe 6" to long.
So what do you do for a driveshaft? Does anyone have any suggestions regarding replacement?

Is there a 1 piece I can use with out having it custom made? Maybe from another make or model? Has anyone encountered ? what did you do?
