[alfa] Re: GTV differential bearing slop

[Bruce Giller <bgiller@xxxxxxxxx>]

Skip,
	Thanks for the reply for I was ready to go out and price a used rear end.  Yes, the slop was almost gone once the
pinion nut was torqued down.  I have done this operation on my '86 Spider but never experienced that degree of slop.
