Rear Differential-2014 Tacoma- 4.0 L 4WD Access Cab 6 speed

Took out my rear differential. It is labeled 3.7. Which I’m assuming means it’s a 3.73 ratio. I see an ad for a differential that has the same ratio, but it’s for a 2WD 2nd Gen Tacoma. Neither has manual or electronic lock-in. Anyone know if this will fit?

 

Was the donor tacoma a 6 lug?

If you have the diff out either count the teeth on both the pinion and ring gear, OR spin the pinion and count the rotations of the pinion until the ring gear takes a full rotation.

 

I'm certain I have a 3.7 differential. Its whether the other diff fits. I'll contact them and se if its a 6 lug.
