madkaw Posted February 27, 2007 Share Posted February 27, 2007 I am installing a r200 in my 71 . In order for the diff to line up with front diff mount I have to pry the diff back about an 1/2". Is this correct? When I do the search I can not seem to come up with a definitive answer. In Carl Becks r200 swap page he talks about two different mounts, but MSA shows one part# for all Z's thru 78. I have made a Ron Tyler mount based on the stock mounting point of the original mount since I am still running the L6. So was I correct in ASSUMING(I hate that word) that this small change in the postion of the diff will not effect anything? Quote Link to comment Share on other sites More sharing options...

madkaw Posted February 28, 2007 Author Share Posted February 28, 2007 I am using a r200 moustache bar. The FAQ says to flip around the front mount. I can't remember what the original positon was. I know that when I flip it one way the mount is off by a couple of inches, the other way it is off by a bolt hole. There is only one r200 moustache bar isn't there?

wheelman Posted February 28, 2007 Share Posted February 28, 2007 Is the mustache bar behind the rear crosslink supports? If not, flip the mustache bar around and then align the front mount to correctly fit. You might have to get a later model rear crosslink as well. I don't remember what year the change was made but Nissan moved the diff back which required the rear crosslink to be curved. If your car is old enough the crosslink will be straight which won't work with the R200. If you can, take some pictures it might help us figure out where the problem is.

Pop N Wood Posted February 28, 2007 Share Posted February 28, 2007 Also make sure the cross piece behind the diff that connects the two control arms is curved and not straight. Quote Link to comment Share on other sites More sharing options...
