Being that I am not home I cannot respond to my own post.
Anyway, last week I found out the hard way that the early wiper pivots are pot
metal when I lost most of the threads. So, I wanted to know if anyone had found
a viable alternative.
ehhhhhh....
I am still waiting on my MGB parts guide to show up but the local Brit place
showed me a pivot from the MGA. It was not compatible and he went on to tell me
that the pivots for all those cars that Moss Motors supplies parts for are the
same. I hope he is wrong when the book shows but I doubt it.
THE VIABLE ALTERNATIVE IS:
**Rework the threads on the nut and the pivot.**
First, I went to a couple machine shops who shrugged their shoulders and told
me to go to the junkyard.
Pffffffff....
Next, was a trip to the hobby shop, Harbor Freight, and Home Depot. Oh yeah,
and one trip to the Pharmacy for 3.25 reading glasses.
I already had a vise and propane tourch so I needed to pick up a jewelers
adjustable saw frame and 61 TPI jewelers saw blades. I would also suggest you
get a wider blade with less teeth too as the thread grooves are wider. At
Harbor Freight I got some small picks and jewelers files.
Cleaning out the threads from the nuts was the easy part. Building the threads
on the bad pivot took me 5 hours. The good thing was that the threads not
touched by the nut gave a good pattern to follow around the pivot with the hand
saw. After cutting the existing threads clean I cut new ones to the end of the
pivot. I then used the pick to clear them out and the jewelers file to open
them up for the nut. After that, it was an alternation between testing the nut
and cleaning the threads out. Finally, with PB Blaster I turned the nut down on
the threads.
The threads are not factory pretty and there are a couple gaps where there are
no threads due to lack of metal to form a good one.
But, the nuts are a firm fit now and when they get back on the car it will be
with antisieze.
Oh, what made me do this? Well, all the time I had into stripping that car and
the thought of trying to get the pivots off my parts car in one piece made me
cringe.
Thanks to Mike Kerr for telling me to heat up the pivot/nut and to use
penetrating oil while they were hot while trying to loosen the nut. That advice
prevented me from having to make threads on the second pivot. I only lost a a
very small segment of thread and the rest cleaned up very nice on the second
pivot with the saw.
