sensors changed but you will be getting bare tb so you use your old sensors im pretty sure only one sensor changed as long as your tb has the 4 bolt pattern an not the renix style where intake hose bolts on it should work

well they stopped renix in 90' so why wouldnt the 91-92 also work?
and im pretty sure there are other differences between the pre99 and post 99 TB's
but, ill have to wait till tomorrow to check a few of the ones i have at the shop.

JNX--- Im out of TBs for a 91, I will let you know when I get another core.Ronnie, also out for your year....will let you know when I have one.I thought that 95 was the year that the MAP was moved on the TB from the firewall, therefore they have the vacuum port on the drivers side. So, 91-94 has no port, 95-01 has the port. Also, I cant bore Renix TBs.
