I am restoring my 65 mustang restomod and I am thinking of converting to a rack and pinion kit by flaming river , anybody have any reviews on this upgrade  

I am considering them as well.  I had an unknown source say they have seal problems, to me this is totally non confirmed.  I would sure like to hear back from others as well.  

See my note on the Randall Rack.  I was totally discusted with their response and have crossed them off my list.

How about TCI.  Seems expensive, are they worth it?

Randall's gave me wonderful customer service so far, and I have no reason to doubt that it will stay that way through my install. Sorry to hear that was not the case for you.

The FR system has been taking a bashing. I have read that bumpsteer is a major issue with that unit and that fitment is tough with most header combos. I have yet to read a single person that has it say that they would do it again.

Others to look at are the TCI, Unisteer, Steeroids. If you want power steering then your best be is going to be Randall's or TCI. I have read good things about both the Steeriods and Unisteer for manual operation.
