Hope someone here may have the part number, or have a unit for sale?

I have an original 70 GTX 440HP auto with PS/power drum brakes that I have been told does not have the original style booster, and after looking at online pics I would agree, mine appears newer and smaller and I don’t feel operates correctly when braking.
Anyone know what model I would need, or can that info be found on my fender tag or original build-sheet that I have?
All input is greatly appreciated
Thanks, Bill
 
I have the booster that came on my 68 Charger with power drum brakes. I had it rebuilt by Booster Dewey and then upgraded to Power Disc brakes so needed the dual diaphragm booster. This is PN 3004608. I'm pretty sure it was used on the 70 models also. I have this complete set-up on FBBO for $250.00. If all you want is the Booster, I will sell it for $200.00. Here are some pics

Here is a conversion kit for B body Mopars for 1966-1970 if this helps? Seems like a reasonable price.

Yup. That is the one I used for my disc brake conversion. Made in China and the rubber boot that goes through the firewall is larger and requires some grinding on the firewall to make it fit. It looks factory and is the dual diaphragm unit. Not needed for drum brakes though.

I think I'm the one who told you that at the Farmington rd cruise.

This is a picture of the same type of booster that is on my drum brake 66 Satellite. Don't for sure its right for a 70.

Here is the one out of my 23000 mile original 70 Charger 500. I always wondered if it's the original being so shiny and all. But at 23000 miles would have it needing replacement??

Do you have pics of the booster that is in your car now?
 
Hopefully someone can identify it. I'm not sure but it looks similar to the one in post #8 only painted black.
