78-80 RX-7s have the shifter in the same location as the early tranny. 81 on
has the shifter moved rearward, which requies modification to the tranny
tunnel.
81 on has cats, pre 81 used thermal reactors. All models use air pumps.
IMHO, the 76 RX-4 tranny, or 76 RX-3 tranny is the best for street use, with
77-78 RX-3 a close third. RX-7 trannys have a weak input shaft that can snap
under hard use. If you aren't abusing the things, 78-80 RX-7 gearboxes are
acceptable.
