Choosing Correct Steering Gear - Rack/Pinion

[xl_cheese]

Looking to replace my rack and pinion due to the clunking I get over low speed bumps. When I search there are so many part numbers that pop up.

Which one should I pick and what exactly are the differences between them? Is it just a programming difference or are there physically different internals? My car was built with 18" wheels, but I have 19x10 on the front aftermarket.

Bump... interesting. Had no idea they differentiated by wheel width. Is this why when I drove my cousin's GT350 the steering felt so light compared to my GT non pp with 275/10" ?

Wouldn't your vin tell the parts guy which setup came with the car?

Yes, but as I said I don't have the stock wheels on any longer. If there's something benefical to one of the others I would rather get that one.

Don't overthink this. Just go with what the car came with. How many people change their rack based on tire size? I will go with 0.0 as the actual number.
