Getting ready to install the column on the 70RR. My search on install found this..

"When all the right parts are used put the coupler on the steering box first, then raise the column to the dash mounting points and barely snug the bolts, align the column and shaft in the engine compartment at the end on the top tube and tighten bolts. Having a helper is easier. Last are the 4 firewall plate bolts."

Any other input pointers etc...? Steering wheel off...

There is a measurement of the shaft to the coupler, so the mount bolts have to stay loose until that is achieved. It's in the Service manual. Read the book very carefully.

Not mentioned is whether the car is column shift or floor shift. The '69 FSM does not cover floor shift columns, and the '70 manual may not either. If your car is floor shift, you have to study what's said about the other columns, then figure out what applies to a floor shift column.

Floor shift.... 70 RR
