Sf differential with e19 date code all original with low mileage
looking to sell for $1500. Or trade for 3:42 or 3:91 w30 differential in similar condition with a late date code. For those who don't know the sf is a 3:23 ratio and it came with the a/c w30's. I accidently sold the wrong one some years ago.

 

It came in any 442, not just the W30. 3.23 was the standard ratio in the 442 in 1970 and could be had either with (SF), or without (SE) posi.
