I have emailed EPAS to determine if the same C1 type setup will fit a 1951 one ton GMC. Lets see what the spectrum of the C1 Corvette allows. Will share results as this seems to be the perfect conversion, if you can afford the $1500!
I think is has to do with the tube diameter of the column. A lot of GM cars and trucks used the (2"?) column tube. This torques off the tube, The self cancelling factory turn signal assembly I'm using came off of a Chevy sedan and it slides right on my 53 3100 column. I shortened my column 3" to use the 54 truck steering wheel with the canceling tab on it. If you are doing the EPAS that might be something to consider at the same time. Please let us know what you find out.
