Ok - I'm doing a rebuild on the trans and the little metal ID tag says "13-52-199"

Also, on the tailhousing it has "13-52-066-919" and the maincase has 13-52-065-908"

The 2nd gear has 31 teeth.

Is this a v8 trans or 4 banger?

The tag shows it to be a 90-91, V8 model T5 rated at 300ft/lbs of torque.
First gear = 3.35:1
Second gear 1.99:1
Thrid gear 1.33:1
Fourth gear 1:1
Fifth gear .68:1

My neighbor seems to believe 31 teeth on 2nd gear means it's a 4cyl (and someone put the original tag back on).....his wife's has 30 teeth on 2nd.

Can you comment on the teeth count?

Both versions are world class. The only Mustangs not to have a WC t-5 were the 1984 and early 1985 Mustangs. Ever since they've all been WC. It only refers to the use of 3-peice synchros and different bearings. That's all.
