I plan to convert my 62 Savoy to power steering also. Initially, I thought I would go with a Borgerson set up but Borgerson told me because I have the 318 poly their conversion package doesn’t work. I’m now thinking I may have to try and locate an original pump and steering box have them rebuilt as necessary and go that route. Would love some advice from someone who has already converted their 62 to power steering. Thanks!To be on the safe side I'd say '62-'64.
The steering shaft is shorter for the power steering. The coupler is a different diameter at the steering box so you need one for power steering. Some are using aftermarket steering boxes. Then whatever steering pump you decide to go with you'll need the correct brackets, hoses, pully. Then at least a double pully for the crank shaft. For a big block, 440 Source has the pullys. And brackets for the Saginaw pump.
I recently converted my '62 to power steering from a manual. I really like it.
