3046moparcoupe Posted October 28, 2018 Report Share Posted October 28, 2018 Hey fellow P15 owners, before I confiscate the two existing holes I just discovered on the drivers side inner fender just below the starter solenoid, to mount some circuit breakers. Maybe someone could tell me what there original purpose was for ? Each hole has a couple of threads (just like the punched in holes up on the drivers side shroud, by the core support, where the headlight t-blk mounts). They are about 2 inches apart, and are located a few inches below the rear (firewall) side of the starter solenoid. Just by the location, I'm guessing maybe some kind of support brkt that braces up the solenoid to starter cable ?? however, nothing was there on the car when I got it. I appreciate the help Steve Quote Link to comment Share on other sites More sharing options...

3046moparcoupe Posted October 29, 2018 Author Report Share Posted October 29, 2018 Thank you Dan, the horn relay on this car was mounted up by the horns themselves, centered between the horn mounting bracket, slightly in front of the top center of the core support. and I've since gone through and re-worked that area and left the relay there. Sounds like I can go ahead and use this spot for my circuit breakers. I appreciate the reply back on this. Many thanks. Steve. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted October 29, 2018 Report Share Posted October 29, 2018 Steve, it is always a help to post a picture (8 x 10 glossy with circles and arrows.....) with the age of these cars and the many times it has changed hands there is no guarantee that the holes in question are stock or part of a "owner fix" somewhere in its history. 1 Quote Link to comment Share on other sites More sharing options...
Young Ed Posted October 31, 2018 Report Share Posted October 31, 2018 the horn relay did move at some point in p15 production from the brace for the hood latch/horns to the inner fender. 1 Quote Link to comment Share on other sites More sharing options...
3046moparcoupe Posted October 31, 2018 Author Report Share Posted October 31, 2018 Thank you Tim and Ed. I appreciate your reply's back,....you both have helped me countless times over the past few years.... and I can appreciate what Tim is saying regarding a picture,...I will do that going forward,...as I'm looking for accurate reply's back, least I can do is my part to try and help insure that enough information is provided to allow that to be possible. Very good point,...not only smart, but wise.. These holes do match up with the hole spacing on the horn relay, and they are an exact physical match (where they just appeared to have punched the sheet metal inward, drilled a hole in the center and threaded the slightly over a 16th inch of curved in sheet metal around the hole, [ maybe 3-4 threads ], ) as the holes also up front on the drivers side shroud sheet metal where the headlight terminal strip mounts... Interesting that these 2 horn relay holes and the 2 holes up front for the headlight t-blk, fit a #6 metric screw perfectly....there must be an old machine screw thread that was a close match to a #6, as I sure wouldn't think they would have used anything metric on these cars originally. Thanks again forum friends.. Steve Quote Link to comment Share on other sites More sharing options...
Eneto-55 Posted October 31, 2018 Report Share Posted October 31, 2018 Metric bolts on an old Plymouth???! Is that worse than using Ford parts? (Just kidding. I am planning to use the antenna mast off of a 93 Chrysler Town & Country to repair the antenna on my 46, and I was pleased to find out that the threads on it are actually standard 1/4-20. MAYBE I would have anyway, even if they were metric...) Quote Link to comment Share on other sites More sharing options...
Andydodge Posted October 31, 2018 Report Share Posted October 31, 2018 METRIC????.........wash your mouth out!.............lol.................what are those two things at the end of your legs?......metres or feet???...........lol.............I throw every metric bolt I find in the garbage bin and have a set of metric spanners & sockets under lock & key lest they escape & infect the correct and pure Imperial tools..............metric?......bah humbug!!..........lol.........better go wash my mouth out now............lol..........regards from Oz......Andyd 1 Quote Link to comment Share on other sites More sharing options...
DonaldSmith Posted October 31, 2018 Report Share Posted October 31, 2018 (edited) I wouldn't touch the metric system wth a 3 meter pole! (Edit: The spark plug holes are metric.) Edited October 31, 2018 by DonaldSmith Quote Link to comment Share on other sites More sharing options...
BobT-47P15 Posted October 31, 2018 Report Share Posted October 31, 2018 I found relays on the firewall of Plymouths from the early 50s. Quote Link to comment Share on other sites More sharing options...
