Hey guys,
I'm doing a manual conversion on my 1999 Legacy B4, and got a box with the ID tag TY752VBCAA, which is from a GTB and has the ratio of 4.444. How do I find out the rear diff ratio of the Legacy (without taking off the backing plate and counting) and if it's not 4.444 would I need to replace it with a diff with a 4.444 ratio?
