If it were me, I would just go with 1350's, because that is what 3/4 and 1 ton chevy's had stock. so the parts are easy to find. All you have to do is get the 1350 yokes off of another 205 or even a 203. the 203 is your best bet for the rear yoke because they are ultra common and most people are glad to part with them. For the front, your '72 205 will most likely have the corse splined output, so you are going to have to find a 1350 yoke out of an old truck. I do not beleive that they ever made a corse slined 4 bolt cv drive flange. I dont think there are any corse splined 203's but I could be wrong.

Hope that helps.
