I've tried searching but haven't had much luck. Recently I purchased an R200 from a 280zx, when it arrived it didn't have the output/side flanges in it. When looking inside I noticed the center had a block in it with a threaded hole. I called the person I bought it from and was told this style didn't have side flanges and the u joint had a long bolt that went through and held it in place rather then a snap ring.
My question is, can I use the snap ring style side flanges in it? If not am I able to have a shop swap the 280z R200 center that uses the snap ring flanges in it without any issue?
Sorry if these sound like dumb questions.
