part number verification

Can anyone verify what vehicle the following parts were used on?

4052836-R and 4052837-L

They are early '80's vintage. and Dodge/Chrysler

Thanks

Going to have to look for other identification - two Chyrsler dealers could not verify that these are charger parts.

These part numbers are probably too old to be in the new dealer system. I will take a look in the "old" mainframe system. Did the Charger have a Mitsubishi counterpart/clone? I don't recall what did and what didn't?

No, they did not have a Mit. counterpart.

While you are at it, can you tell me the difference between 4273099, 4273100, and 5203750? They are all exhaust manifolds. ...3099 is what the 84 parts book calls out, I've got a ...3100 that looks a lot better (center two ports are more like individual runners, but it has a big blob of metal on one side that doesn't look like it does anything), and ...3750 looks pretty plain.

Thanks.

Just put a header on it.....and exhaust all your worries away !! B)

The numbers you originally provided are for the casting only. Give the dealer these numbers and see if anything happens. I can't get any more detail than that. So hopefully only one works and it is the correct one that you need.

4273100 is just the casting number for the 4273099 manifold according to the system.

5203750 looks like a newer number or a fastener number. It might actually be a number assigned to some aftermarket made exhaust manifold that Mopar buys and rebadges. Whatever it is I can't find it in the system. Sometimes mopar did make their own numbers for their aftermarket purchased stuff.
