Installation of the newer column did require one slight mod- the mounting plate was mostly flat and the 79 firewall curves back on the lower right as pictured. A few light taps with a hammer curved the plate to match the firewall contour and all the bolts then lined up fine. As I said before, overall this was an easy install.
Once all the wiring and fitting it in place was done, I prepped the ugly brown 85 steering column by hitting it with 320 grit paper, then a quick once over with wax and grease remover and I rattle canned it with semi gloss black. My Grant steering wheel replaced the goofy factory unit.
Here's the final install. I'll be keeping my eye out for a column from a floor shift car here in GA, as I never saw one in the junkyards in Utah...
