rack n pinion swap

[mauve66]

i find setups for 68up b bodies but any reason it wouldn't work for a 66?? same k frame and other steering parts in the same place, right??  or wrong???

Sorta. They use similar parts in the same places, but the 66-67 models used a different idler arm mount that may not be compatible with the rack mount design of a post '68 system.


IMO, just a simple rack conversion is really not a performance enhancement without converting to a whole new front suspesion system. My logic for that is the rack has a reduced turning radius compared to the stock box. It also may, depending on several factors, increase bumpsteer characteristics. While its feel compared to an old or even a basic rebuilt box may be superior, that can be overcome with a better stock style box, like a Firm Feel,  or a conversion to the newer Delphi units. In those regard, the only advantage the rack has is lighter weight and the Delphi box is coming close to that.

Agree.

R/P conversion isn't the best way to tighten up the steering if that's all you're after.  Fresh tightened up (Mopar) steering box + more caster in the suspension works fine.

my r & p works just fine,had to do some mods to make it work correctly ,but glad i went with it    its not a direct bolt on like they say in the instructions,but all the problems are fixable . yes mine has the same turning radius as a gear box.

thnaks, firm feel box will be cheaper i'm guessing also
delphi - just comes up under a bunch of threads, no manufacturer site???

Anything is workable, but with the high number of bolt and go enthusiasts today, I've seen many more reports of disappointment than satisfaction.

Delphi stuff can be picked up from Summit, but is not a cheap swap, especially compared to a Firm Feel, Good read on it here:
