Newbie with ignition question
Congrats on the low-miles find. My own '73 Dart Custom 4-door is a "high miles" unit compared to yours (50k original). It's not 100% clear what exactly you're looking for; that "part number" has too many digits. Chrysler part numbers in the applicable year range have seven digits. I am guessing your P/N is in fact 3874 300 and the "454" is a date code. I am further guessing this what you're after is mounted on the firewall, somewhere between the middle and the passenger side.
P/N 3874 300 is an EGR timer module. I'm betting it looks like one of the two boxes in this picture (disregarding the stamped P/Ns):
Please confirm or correct that guess.
A couple of questions:
1. Is this '75 equipped with a catalytic converter? Does it have "UNLEADED GASOLINE ONLY" labels near the fuel cap and on the dashboard? The '75 models came both with and without catalysts, depending on engine and other equipment.
2. What regulations does the state of Maryland apply to 1975-model cars like yours with respect to emissions? Do they do a tailpipe test? Do they specifically require that all original-equipment emission control devices and components be present? Please be specific, and check into it if you're not sure. It matters to what advice is given for your repair.
3. What is the trouble with the part you are trying to replace?
