Wrench Fetcher
Not sure if this will help but I just installed the Patrick's 3.55 gear and pinion in my 48 truck last weekend. Followed the stovebolt tech tip which called for placing the Torque tube in a vertical position ( I strapped it to a 6' ladder with 5 gallon bucket and with board across it ) and insert the shaft with the pinion gear assembly into the tube from above.
Following the detailed instructions I was able to line up the three bolts that hold the bearing retainer in place.
