To be honest, without digging up a copy of the article I am not positive what exactly I said to do. But some of the approaches that I used then that I don't do now...
The FJ60 arm has a lot of drop and clearances get tight. I have modified FJ40 arms... cutting them and turning the end 180*. A better solution is an FJ80 arm.
On at least one of the early conversions I wound up having to cut the radiator mount some for clearance. If you uses a full 3/4 inch plate, it move the box out far enough that it fits without clearancing.
The Ford f250 shock mounts work a lot better than the fabricated from steel stock that I did a few times back then.
Depending on your exact setup, it might work better to make the mounting plate long enough to mount the shock tower on it too. Clearance between the ford shock tower and the steering shaft can be tight.
I have come to not like the positioning of the steering wheel when you use a full length FJ55 steering column. Shortening it a bit makes for a much nicer setup. personally I still like the all Toyota approach over using an aftermarket steering column. but I also like a swapped in mini-truck column with the smaller steering wheel, tilt steering and all the controls on the column... I hate reaching for the wiper switch in a 40 on a dark road in a snowstorm.
If I think of anything else that I don't like anymore about the way I was doing that conversion back then, I will add it later.
