1969 Autolite 1101 Air Cleaner won't fit

[velvetguru]

I have an Autolite 1101 that I took off of a 1969 Mustang 250, I got the air cleaner too (it was sitting inside the car) but it's too big for the carb. Is their some sort of spacer/adaptor or something that goes between the air cleaner and carb that I'm missing?

Thanks,
Joe
