I have a 1985 hatchback. So basically it is more like the older generation. Tried to replace the CV axles and the shop got the wrong ones. Anyone know of a good source for these and also how to let them know how many splines I need? Basically, is there any way other than pulling the axle back up and counting the splines from the transmission of knowing which ones I should order?

I think I count 23 on the axel. So now I need to know what the compressed length should be. Basically, one of them didn’t fit the splines and the other one was too long. And please let me know if you have a preferred source.
