Friend of mine just showed up about an hour ago saying he had something for me. It was a rearend, eventhough I've already ordered a gear set. But the id tag reads as follows
S390D 373 A75 8E04
Can anyone tell me what this is out of? He knew I was looking for a set of 3.73 gears. But I'm just curious for my learning curve, is this an 8.8 in. rearend and would it have worked in my 88 Mustang 5.0?
