Modifying Auto on the Column Steering Collars - NO Welding Required!!
yep its a good idea. i have done this in the past as well. in fact i just did this on my 67 cuda column i converted from a 3 on the tree, in the past i took a late model diecast GM tilt column out of a 74 monte carlo i was putting in my 60 el camino, and removed all the ignition stuff from the column, shaved and filled the lock key hole in the column, as i wanted the tilt, but wanted the ignition key left in the dash
On the later A body cars with the ignition switch in the column, i would recommend looking for late 70s to early 80s dodge pickups if your junkyard has any available, the late 70s early 80s model dodge pickups with a floor shift either a 3/4 ton or 1 ton with a top loader, or a 1/2 ton with a 4 speed, the collars are already smoothed, its just a matter of removing them from the truck steering column, sandblasting and repainting them. they fit right on an A body column.
a manual column shift 3 speed pickup column will work too, you just have to fill in the one shifter hole on the lower collar.
i have redone automatic transmission column shifter ones for 67 to 69 model cars with the JB weld too. it works great. i would recommend against using fiberglass filler, and or bondo, unless the bondo is just for smoothing out imperfections over the JB weld filler. by itself the bondo will eventually crack.
i was going to cut down a set of column shifter collars to make a floor shifter column for a 70 up A body to resell, but came across a set of dodge pickup collars off a 79 dodge 1 ton dually with a toploader in the junkyard. it was a matter of sandblast and paint and assemble.
the job you did on yours is really good. i abandoned this method for the column i was redoing due to the shear time and effort to smooth them out. kudos to you on yours tho.
i hope this helps someone out
