1970 Duster project in Sweden
The 70 up columns require more cutting and grinding to smooth them than the 67 to 69 ones, however there is enough metal there to grind off and shape.
Pix below are of a 67 - 69 column shift one i cut and reshaped. I ended up finding factory floor shift ones to use, so i planned on putting these up for sale. In the upper right picture, you can see the metalized epoxy putty filling the indicator hole from the inside. The key to it really bonding is to super clean the metal of the part where your putting the metal epoxy, then rough sand or grind where the putty will fill the hole so it bonds well. i also grind and file the diecast slightly concave where the filler goes, and let the filler overlap the diecast, so there isnt a hard parting line between the 2 materials.
Got this idea from an old hot rodder who had a 57 chevy bel air with a mid 70s GM tilt column. He kept the tilt column, but removed the ignition key from the column, shaved the metal down and filled it the same way, and kept the key on the dashboard.
