Using a 29 housing just requires the brake backing plates being changed as they are different, to accommodate the two piece external brake band.
I picked up a 29 housing a while back, in very good condition, and now the strip and clean begins.
6 rivets on each backing plate need to be ground down then driven out with a pin punch.
This is new, never done it before, never too old to learn.
Like a few Chev Rear axle housings I have seen, the saddle location fitting works itself a bit lose and starts leaking oil. The problem is easily fixed with a complete weld around the fitting and a bit of peening of the rivet head.
This is the 4th time, including Monty the 28 Chev, that I have removed the rear axle inner seals, and by far was the easiest, thanks to a home made slide hammer that Grant Fowler's late father, Wayne Fowler made many years ago, and no doubt served him well.
It is now an official Chev restoration tool.
Wish I had one during the original 1973 restoration and the 2007 restoration for my daughters wedding.
Thanks Grant, and your Dad also.
