[FC] Shift tube R&R

[Rad Davis]

I don't know of a single universally-performed procedure.  Stuff I've 
seen or heard of being done:

1) drill the two holes in the tube oversize.  Then drill the shift bar 
in the trans oversize to match.  Use a hard steel long-shanked bolt 
suitably modified as your clevis pin.

2) there's a procedure involving sleeving the shift bar back to stock 
after drilling oversize with brass tubing stock.  This provides a large 
bearing surface for the shift bar.  You could do something similar with 
the shift tube as well.

3) I'd probably braze the holes up if I wanted to go back with the stock 
pin.  A brazed surface is a natural bearing surface--corrosion resistant 
too.  You generally want a hard metal in contact with a soft metal for 
sliding bearings, and bronze, while hard, is softer than a grade 5 
bolt.  Braze and then drill back to stock size.  Mapp gas is sufficient 
if your propane torch isn't up to the job.
