61farnham Posted March 28, 2017 Report Share Posted March 28, 2017 Hi all, Finally found some time to work on the Plymouth. I was busy chipping the some old underseal away when I uncovered a painted no. stencilled on the frame upside down in red, it's on the drivers side outside rail mid point of the car. I'm guessing it's the frame no. from when the car was manufactured can anyone out there decipher it for me? It reads 3-23-48-78-30 The car's a '48 Bus. Coupe built in L.A. if thats any help. Regards.......... Simon. Quote Link to comment Share on other sites More sharing options...
casper50 Posted March 28, 2017 Report Share Posted March 28, 2017 frame numbers are stamped not painted. Also should be on the rear wheel arch driver's side. 1 Quote Link to comment Share on other sites More sharing options...

Thanks for that I'll have a look tomorrow, would that be stamped on the inside or outside of the frame? Anyone else got any clue to what the painted no's for? It's been hiding under that underseal for a long time. Simon. Quote Link to comment Share on other sites More sharing options...
casper50 Posted March 28, 2017 Report Share Posted March 28, 2017 mine is on the outside. Quote Link to comment Share on other sites More sharing options...
61spit Posted March 28, 2017 Report Share Posted March 28, 2017 Looks like a date stenciled on there. March 23, 1948 (3-23-48) and then the last two numbers. Could it have been something stenciled on a stack of frames that were delivered to the assembly line? I thought that the number that is stamped into the frame rail matched the engine number. I know mine does on my 53 Suburban. 1 Quote Link to comment Share on other sites More sharing options...

Ricky Luke Posted March 28, 2017 Report Share Posted March 28, 2017 On my 40 Chrysler C25 the chassis number is stamped on the RHS of the frame in front of the suspension https://www.dropbox.com/s/x5e9dnwo9bf1p6y/Note_20131119_001326_1.pdf?dl=0 Rick 2 Quote Link to comment Share on other sites More sharing options...

Had a close look round the rear of the frame and can find no number stamped into it, front end is still coated in underseal and that's for another day!!!! Thanks..........

casper50 Posted March 29, 2017 Report Share Posted March 29, 2017 it's suppose to be drivers side outside rail above or just before the rear axle hump Quote Link to comment Share on other sites More sharing options...

Thanks all for your input, double checked not there on mine perhaps they did things differently on L.A. built cars? regards.... Simon.

Simon. My Plymouth was not built in LA. My 1939 Plymouth Truck had the number on the left from frame horn. To be honest, I had to wire wheel deep to find my serial number. Seems like the factory paint "hid" them from me.... Hopefully this will be the same case for you. 1 Quote Link to comment Share on other sites More sharing options...
JerseyHarold Posted March 31, 2017 Report Share Posted March 31, 2017 It may help if you use a bright LED flashlight at various angles along the frame rail to see if you can spot the stamped numbers. 1 Quote Link to comment Share on other sites More sharing options...

You're not kidding about the factory paint hiding it, found it today just in front of the fuel filler pipe with a combination of a wire brush a bright torch and me reading glasses!!!!! Reads P15 682197 which is different to the engine no. which is P15 995471 so obviously the engines been replaced at some point in the cars life. Thanks all for your help.

Niel Hoback Posted March 31, 2017 Report Share Posted March 31, 2017 Another mystery solved. It's quite common to see mismatched numbers because changing engines was, and is, the quick easy way to do a rebuild. Every one from the shade tree mechanic to the dealer would toss in a rebuilt engine in a few hours rather than remove strip and rebuild the original one. Yours looks like an exceptionally well preserved frame. 1 Quote Link to comment Share on other sites More sharing options...

I think the usual Australian location is on the left below the cowl. Quote Link to comment Share on other sites More sharing options...
Ricky Luke Posted April 9, 2017 Report Share Posted April 9, 2017 I'm sure. Took me a long time to find it. It's a hand stamped number that equates to a 1940 Windsor. There's another tag by the body builder (TJ Richards) on the cowl. Rick Quote Link to comment Share on other sites More sharing options...
