Screwed up master cylinder threads-replace part?
I rebuilt my '51 F1 master cylinder and then stupidly crossthreaded one of the lines into the brass fittling at the end of the master cylinder. Totally stripped.
Question: Can I get a replacement brass part (the thing with the three threaded ports in it), or must I get a whole new master cylinder?
If so, where would I obtain that part? Would my FLAPS have it?

A number of places should have it. I know the JobLot Automotive (www.joblotauto.com) does - part number 8C-2076 for $5.95.

hey Chicowoodhill,
While your at it go ahead and get all new washers and brass fittings that you dont have for the rebuild. And dont forget the brass line fitting on the rear diff (if your truck has one)
your new lines will seat better on fresh surfaces and will only cost a few dollars...not blood-pressure points!

Good catch Ed. I missed that one - new copper washers are a must. Some folks try to heat the old ones up and then slowly cool them so they can reuse 'em. Seems like kind of a bad idea when new ones are something like 50 cents each.

Just a side note to this discussion. About four years ago I replaced the master cylinder on my F-2. I did it on a Sunday afternoon and wanted to get done early enough to take it for a spin. I finger tightened the lines into the brass block and then wrenched them tight. After I filled the cylinder with fluid I hit the brakes and heard a dreaded hissing sound as the brakes went to the floor. I checked and I somehow cross thread the top fitting. I really wanted the truck running so I went over to my parts supply, or as my wife calls it, "Your pile of junk. Why do you have to keep all that junk on that shelf, there isn't anything in there that is of use." Well, within five minutes I found an old master cylinder with a block in very good condition. I told her "that's why I keep all that "junk". Saving all my "useless" part has saved me a lot of time by not having to run around to vanishing junk yards and waiting weeks to find a part.
