Im going to replace the rack n pinion and it calls for with or without performance suspension. I really doubt it matters, but how do I tell? Is there an RPO code or VIN digit. I think I should be able to use either one. The only difference I noted was the ratio. One was 20:1 and the other was 15:1. Obvioulsy Id like to put the faster ratio on.

TIA
