restated question about spacer part

[tracterman2]

Okay the 307 with the two barrel and powerglide..I want to keep it orignal...it is a missing the adapter or spacer between the carb and the air cleaner...what does it do...what does it look like?? Does anyone know where I can buy a new one?? If no one does I'll post it...I'm going to join the forum as a supporter regardless soon...just haven't had a chance yet...need a little info on this little piece...I didn't know I needed it until I tried to put it all together tonight....the air cleaner will not clear the fuel line going into the carb...any info would be appreciated.

Thanks
