Welcome to the site. I can't help you with your swap much, hopefully someone can. We do have a Toro section so check it out and good luck with your project.

The early Toronado didn't use a full length frame. I don't know If the 1971 partial frame would interchange. But I think it would be easier to locate which years of disc brake setups would interchange and make that swap in the front. Then use an aftermarket disc setup for the rear axle. A couple members have done major build threads on their Toronado restorations. When you have time read through to see what they did about brakes. Here's a link to one that comes to mind. John
