I am so sorry to hear of your loss. . .

Have your bookmarks been updated to the new URL?

No wonder my search failed. . . I kept trying variations on "Capt" User ID is "Cpt.Fred".

Looks like a body mount to me and I suspect you'll need to weld in new metal. I think veterntechnic is in your general part of the world and from his restoration thread it seems he really knows what he is doing: http://p15-d24.com/topic/30811-restorating-a-p-15-business-coupe/?hl=restorating You might want to contact him. There is an other forum member who posts from Germany but I am having trouble remembering exactly how he spells his screen name. If I can't find it, I am sure that others will post here too.

Horse and carriage days: The board between you and the horses that keeps stuff from being dashed up on you.

I like that mount and I like that tach. Maybe, just maybe, I'll get the same setup for my '33. For those with trucks with 4.11 rear end ratios: My '33 has its original 4.375 rear end and the mounted diameter of the skinny 17" wheels is very close to that of the later 16-600 tires. I've had my car up to 70 per the GPS and run it at 60 on a regular basis. If you are only able to do 45 then something is wrong.

One thing I noticed is that the domain name changed and my old bookmark lead to what looked like the current site but I could not log in. You might want to verify that your bookmark now points to http://p15-d24.com/

Looks like the Sisson type automatic choke unit.

Maybe we ought to have a separate thread for answers to Don's signature questions to avoid scattering them around all these other threads. . .

I guess I got lucky: My engine number matches the one listed on the build card.

I've done "a bit of research and reading" for myself. I haven't found links that I thought explained the situation to be as you describe, so I am now asking for links because I am obviously not finding the information you are basing your statements on.

I am in Merle's camp on the size of the brake lines affecting this. But I sure would like to read some engineering based documents explaining why Merle and I are wrong, can you share some of the links you refer to?

Pretty easy to tell as all 1934 through 1941 Plymouths came with a 201 cu. in. engine. (1934 block is different from 1935-41 but the crank, rods, pistons, etc. are the same.) Of course your engine could have been bored out at some time in the past which would increase the displacement slightly.

Here you go... 1937P4WiringDiagram.pdf

Look at your brake pedal linkages and you can figure out how much mechanical advantage you have. Multiply that by how much force a big adult could press down with one foot when in a emergency situation. That gives you the force into the master cylinder. If I recall correctly, the linkage on my '33 gives at least a 10 to 1 advantage. I figure if I was in a panic situation I could press 300 lbs with my right leg. So you are up to 3000 pounds. Now look at the surface area of the master cylinder piston. A 1 /18" diameter piston has a surface area of very close to 1 sq. inch. Divide the force by the area to get PSI. So that would be 3000 psi using my example numbers. Pick your own numbers. But when selecting components, I'd probably at least double that number just to be safe. No clue to the equivalent calculations for power assist or anti-lock braking as the forces there depend on the design of the booster, etc. which I've never much thought about or looked into.

I guess the 15 to 20 psi that you can get those sprayers up to might be enough. . . Hadn't thought of that one nor remembered the earlier post.

Wix stopped making that one about 10 or 15 years ago so it is no longer available at your local parts store. Roberts lists them in their catalog but I don't know where they are getting them from. The sealed canister types are supposed to have a depth media of packed cellulose. My worry about old stock on those is that there are small critters that are perfectly happy to eat cellulose so there may be no actual filter material in the canister and no real way to check.

That would be a judgement call. If there were just a little surface rust around the fitting and it looked like the inside was clean, I'd probably use it. But if there were any evidence of rust on the inside, I'd scrap it.

Actually, the 1934 PE (DeLuxe) Plymouth was fitted with an automatic choke.

Isn't it just a standard welch plug? Should be able to walk into any half decent auto supply or industrial supply and get as many as you need. If you ask for a part for a '50 Dodge it will simply confuse the matter, ask for a welch/freeze plug for a 1" (or what ever you carefully measured) hole.

For what it is worth, my '33 came with 1/4" lines for the brakes. Are the lines on this car original? Could there be a rust pinhole in them somewhere? A soft pedal is basically something giving while under pressure. The most likely thing in a hydraulic brake system is compressible air in the lines. But it could be a rubber hose slightly expanding under pressure because it has broken down and is not as strong as it should be. It could be the brake shoes are have a different arc than the drums and are bending slightly to conform to the drum when under pressure. It could be the drums have been turned too far and are weak enough to expand slightly under pressure. My money is still on air in the lines though. Darned tough to get it all out sometimes, especially if you are using DOT5 (silicone) brake fluid and aren't really careful not to entrain air in it as you pour it into the master cylinder.

I was under the impression that Speedi-Sleeves were available in myriad sizes and you simply selected them by required diameter. That certainly is the impression I get looking at the SKF web site. Is the machine shop looking in an automotive application guide or simply measuring and undamaged portion of the shaft and matching that up to what is in the industrial equipment repair specifications in the Speedi-Sleeve application guide?

Oh well. Nothing I've done in the old Plymouth matches that so I guess I should just sit quite. But I did drive it from Maryland to California "way back when" and more recently did a 2100 mile round trip to the POC meet in Tucson.

Hmmmm. I wonder if those pins are case hardened and if they had to go through the hardening to get is small enough to fit.

I can change that for you if you'd like.
