Is it like 29/87 ish?
If the kit spur hasn't changed from the FT to the R it would be an 87 spur and no pinions come with the kit. When I built my FT I put on one of my 69's and put on a 37 pinion. Thats geared to 3.6
my 1:1 car standard is geared to 3.54.
I've got a couple questions,
Is the spring for the diff critical for the running of the diff, I could only build my diff's without the spring. But they are only the plastic diff's and are going to replaced by an alloy and spool.
Also is the Aluminum Diff Kit (31182) a complete diff? And is the Spool Kit (31179) a solid axle? I don't want a slipper, just a solid axle.
Are the ITF upper and lower decks the ones that come with the R?
