Tubbing the Valiant

I've had a design set back and could use your advice.

I need to cut some of the transmission hump out to get the clearance and better align the drive shaft. With out cutting the hump and having 0.250" clearance I had a drive shaft angle of 10 degree. I understand it should be 5 degree max or less. As you see it in the picture I'm down to about 3 degree and still need some hump to transmission clearance. I figure if I have to cut out any hump material I might as well try for the best drive shaft alignment I can (0.050 or 1.000 degree). I may have to cut more towards the rear of the car as well. Is there a company that can supply replacement drive shaft hump sheet metal to make "capping" it off easier? Or I'm I looking at more custom work?

I don't believe you want the driveshaft aligned to less than 1 degree. The idea is to run both joints at an angle but 'in phase'. Normally the pinion is set up around 2 degrees down from the prop yoke to allow for suspension movement. The angled joints give better u/j longevity.
