1969 Barracuda 340 Formula S Restoration
Steering column was next on the list. They nylon shear pins were sheared off on the centre shaft, so I had to find an alternative method of securing the shaft. The Chrysler TSB for the repair involves using a primer and a Loctite product to put in between the inner and outer section. This supposedly gives the right shear force of about 500 lbs. Some people pin the shaft together, so I did some checks and a 1/8" aluminum pop rivet shears at about 150 lbs. That is a safe number and seems to hold the 2 sections together quite well. I drilled part way thru the inner shaft, drove in two pins, cut them off and peened it. Then for added security applied a little epoxy over it. My upper/lower bearings were OK. Just cleaned and relubed. Ready to assemble.
