Yup.

I believe I still have it if the OP wants it for his. Will ad this air cleaner with the nipple on the air bath cover did come from a 2 ton truck.

I guess I should say that those vehicles with road draft tubes had to be retrofitted for closed crankcase. It actually wouldn't surprise me if some had PCV systems but were still open. Thanks for the correction!
