q-jet base plate interchangeability

(1/3) > >>

beertracker:
This is about q-jet base plate interchangeability.   I have a q-jet main body 17057274 with base plate 60, V, N, P inside a circle, then RP.   My base plate is damaged and I need another one.   Are there other base plates I can use with my main body or do I have to find a base plate with the same numbers  as the original one?

Is there a cross reference table showing which base plates will work with main bodies?  bt

 I would find a core Qjet, with the correct base plate. Interchange is sometimes not good. The part number for you carb number is 17054435. Collector's Auto Supply lists the part number as available. So, I would try contacting them. Also, what exactly is wrong with your base plate?

I looked up this number 17054435 in cliff's book and it decoded as:

4= 1974
4= california
3= Cadillac

So the base plate for the above carb will work with my Pontiac q-jet main body 17057274?  I will follow up with Collector's Auto Supply. 

My old base plate has a rusted in,  broken idle mix screw that won't come out.  The base plate is not repairable.  It was like this when I acquired the carb.  So I need a replacement base plate.

 Should have more clear. Part number 17054435 is the part number for the base plate. Not a carburetor ID number. Part number 17054435 is the correct base plate for your 17057274.

 Though, you will probably pay A LOT more for a NOS base plate, instead of finding a correct core.
