Ignition

I have a 51 dodge truck b-3-c . The points are not firing and I need to replace . I would much rather go electric but pertroinc doesn’t show 1951 in catalog ? What other options are there ???

This should likely be posted on the truck forum but answer is kind of universal. You need to look up petronix by the distributor# rather than vehicle. Who knows if it's been changed over the years. Beyond that if you are going 12v you can convert a /6 distributor or someone sells a chevy unit.

Might want to read up on Pertronix on this site, lots of issues with it failing.

It’s been converted to 12 already and I don’t see any marking in the distributor ???

Points are pretty simple and easy to troubleshoot.why jump into something that isnt quite so dependable,and for a lot more money?

with your distributor number you can locate points and condenser on rock auto or any auto parts supplier.

good chance the ID plate is underneath or bottom of dist

For what its worth I installed a Langdons HEI distributor on the 1941 Plymouth I had....it had been converted to 12 volts before I bought it and as all RHD cars are it originally had a starter button on the dash however when it was converted to 12 volts it had a later key start ignition installed.....anyway prior to the HEI it was a matter of winding the starter over, bit or choke, playing with the gas pedal & it would start ..........after installing the HEI with 45thou plug gaps I could stand outside of the car, lean in thru the open drivers window and turn the key......varoom!!!!!!........... instant start........I would thoroughly recommend the Langdons HEI, this was on a 1941 201 engine, essentially stock but with a Oz GM Holden single barrel Stromberg carby, again that the car came with..........these carbys are a standard replacement here in Oz for the Carter/Ball & Ball as they were used from the late 40's thru to the late 70's and are a bolt on replacement..........anyway the Langdons HEI worked a treat........andyd

Probably need to pull the distributor....

On my car it is impossible to see the mfg. tag when in the car. Even to tell that it exists.

 

2nd. the -remove the dist. and take a real good look!
