75 Volare

I read its an F-body, and there is some confusion as to " Proper Geometry " of the spindle. My question now would be if I use the donar a-arms, just the upper, the lower , I havent seen the donar car yet it is supposed to be in the end of this week. I would like to be able to know what I should grab off of it if anything. The guy said its a 75 and from what I found they didnt come out until 76.
