<font size="2"><font face="Comic Sans MS">1st up welcome,
The carbies you have are a Zenith/ Stromberg CD 175 the CD bit refers to them being a constant depression type carbie and the 175 bit means it is a 1 3/4" carbie the bolt pattern is the same as for SU 1 3/4" carbies so the filters are largely interchangeable (Though I have had to drill extra holes the backing plates of filters meant to specially suit SU's to adapt them to fit Strombies as not all after-market filters are drilled for both)
Now I'm guessing you are from the US (It helps us help you if you say where you are. we don't need your address just city, state or province would do)There are a number of possibilities for you but we need to know where you are so those of us with local knowledge most relevant to you can assist you.</font id="Comic Sans MS"></font id="size2">
