10 spline C6

I'm in the process of doing a manual to C6 swap in my 74 and I just picked up a C6 from a 1970 2wd bumpside the other day.
I got it home and it appears to be a 10 spline.

Is this rare?

Scroll down to 7060 in these two truck parts catalog pics (1964/72 & 1973/79) and take a look-see.

Click on pics twice to enlarge them, then move them around w/the cursor.

Thank you sir. Now for the million dollar question that shows my inexperience. What' the easiest way to get the drive shaft on my 74 to mate with that style yoke on the c6? Have the driveshaft modified? Or is there a 10 spline replacement yoke that would match up?

You will need a Flange yoke to fit the yoke on the transmission that has the u joint size on your driveshaft. You should have a spicer U joint 5-153x. This is a Sample Flange number, this is for a 1310 U joint which yours should be. Not sure if the bolt dimensions are correct though. spicer 2-2-939

Just make sure there is a slip yoke somewhere in the driveshaft. Can be in the front if one piece shaft. Needs to be in rear on two piece shaft.
