Ouch! Driveshaft and Yoke 1310 & 1350 Questions

Busted the tranny yoke which in turn took-out the tail shaft housing and gouged the hell out of the carbon fiber drive shaft. So, questions.

M20 transmission, 3.08 rear-end in a 1969. Engine is a built 383.

The yoke “was” a cast 1310 two part carrying 1-1/16 caps x 3-1/4 U-joints.

Going to the various web sites (Mark Williams & Strange) I can get a 1350 two part chrome-moly part carrying 1-3/16 caps x 3-5/8 U-joints.

Is there a good option to upgrade the slip yoke without changing the drive line to the larger U-joints?

What is the probability that the larger U-joints will have interference problems?

If I do go to larger U-joints, and since at this time it is not practical to change-out the input on the rear differential, I will need to use as combo 1310/1350 U-joint. Will this cause vibration problems?

I assume that I can get a larger input to the rear-end since, it is my understanding, the auto transmissions also used the larger U-joints. Comments or confirmation?

As always, thank you all in advance.

George,

When it came time for me to get detailed information, parts, or work done I spoke with Denny at Denny's Drive Shaft's. I had my drive shaft balanced and new u-joints installed, my slip yoke polished and purchased two new half shafts with u-joints and flanges installed. Here's the web site:
