I imagine there are people here who already know this but since I am new to the Torino community and found out the hard way about rebuilding parts, so I thought it would be a good idea to share.
If anyone owns a 1972 ford with the loose and boat like steering during your drives then this will catch your attention. I wanted my Gran torino's steering tighter with a closer steering ratio. I searched for awhile and found a guy in Missouri who can rebuild and up-grade to a quick-turn ratio steering gearbox. Of course I took off my gearbox and sent it to this guy named "Chip". I give Chip a call and he verifies my gearbox and what car it is for then he tells me it is a Ford steering gearbox and it can't be up graded to the quick-ratio gearing but only rebuilt. We had a longer conversation and he said Ford had two types of steering gearboxes in the 70's, the "Ford" and "saginaw" gearboxes. Both of these can be rebult and also found at your local parts store, but only the "Saginaw" gearbox can be upgraded to the quick-ratio gearing. He told me what year and models car to look for that will have this Saginaw gearbox. I found one not more than 30 minutes after we spoke on the phone, I was relieved but lost out on the shipping on the first gearbox. A lesson learned and I hope it helps other before they charge into a project like this uniformed.
