Took the front end parts off a 93 dodge dakota for the IC IFS swap. There was no R&P. Brakes and arms only etc.

Looking on a few vendor sites there are multiple models of the rack and pinion depending on year. Supposedly even in 1993 there was a crossover month.

The Rack and Pinions

There are a few ratios available and there are even non-assisted racks. To keep it simple, the earlier 1987-1990 Dakota trucks have a 14mm X 1.5 thread pitch on the tie rods and have a smaller stud and nut on the tie rod end requiring a 3/4″ wrench. The 1991-1996 Dakota trucks have a 15mm X 1.5 thread on the tie rods and a larger stud and nut on the tie rod ends requiring a 7/8″ wrench. There does not appear to be a strength issue with either, I suspect this had to do with the Viper connection more than anything else. If you are going to mix and match parts, be aware that your rack and spindles must match. If you are using dropped spindles and have a 1990-1996 Dakota donor, we recommend you use the 1987-1990 spindles as the bore for the tie rod end is smaller. You will need to drill out the steering arm to 5/8″ for the tie rod drop. If you have the 1991-1996 spindle, the tie rod bore is larger than 5/8″ and could cause issue.

So kinda confused what determines which one to use. I figured the R&P and the TRE need to match in terms of thread pitch ...... but asides that the main thing would be the "bore" size on the spindle.
I measured mine and it looks close to 16mm or 5/8. I dont know if this varies between years.

Any ideas on how to track which R&P I need to order ??

IN the notes it says ....
DODGE DAKOTA 1993 2WD; AFTER 7/12/93

Rockauto doesn't show that but there are lots of variations in model #'s listed across years.
