NP205 Front Flange Question

I still haven't put the front axle in my YJ, but i have a question about the front flange on my 205. How hard will it be to adapt a 1310 driveshaft to this? I don't really know much about this style flange. The conversion yokes seem to be pretty pricey for the 205's. Google doesn't come up with much either, i found this pic on another site since i don't have a shot of mine handy...

Just have a driveshaft made with the GM 3R CV and it will bolt to it.

Drive shaft super store sells a 1310 yolk for a 32 spline 205 for $65.00. If it's a 10 spline add $100.00 to that, ouch.

To avoid output shaft changes they sell a 1310 30 spline yolk for $150.00. The original 30 spline output is a fairly strong piece. If it's a 10 spline change it out like Jeepaholic said.

Buy a ford 205 and swap the output shaft and then you can use a 32 spline yoke and have a stronger output.

He's still going to need a driveshaft, so why not spare the extra expense of another case and the work to swap the output and just buy a driveshaft that's correct for the flange?

Just get the driveshaft from a 77-87 chevy, it will have the 3R CV to go to the flange and a 1310 joint on axle side, it will just need to be extended for the YJ.

Cool thanks guys. I actually think its the 30 spline version. According to the years i looked up it should be. The case is from a 77' Chevy behind a SM465. The input however from the trans is 10 spline. The info i really wanted was what it was called. GM 3R Thanks again guys!
