[FC] FC powertrain WITH late car components

[N2VZD at aol.com]

IF you run a late differential in an FC , the axles will both bind up on  
the last few threads of tightening the wheel bearing retainers!. I ran late  
differential parts several years ago because parts were from  very low  
mileage units...and did a LOT of checking to figure out why the axles would not  
turn at all after the last tightening . This was 2 separate vehicles at the 
same  time. I made spacers to go between the backing plates and the control 
arm , but  after a few thousand miles , I put the correct cases AND axle 
side carrier parts  in. It was stressing the axle bearings. I still have the 
leftover parts here  from that simple? nitemare idea.
My advise is get the right differential..I  wrote about this several years 
ago..and when thinking how good an idea it was ,  posted pictures of the 
spacers etc on the website   _http://corvair.de/n2vzd/_

Hope this saves you a lot of trouble.... FACT  the axle will be out  over 
1/4 inch too far with a late differential...which pushes hard on the outer  
bearing race...binding it up in most cases. plus the speedo issue if a late 
car  case. (there is always electronic speedometer if so inclined).
