Its been a while since I switched from 19 to 24 but I think I ordered it from C&L. I should still have it if your interested. I haven't looked for it in about 10 years?, but it should be with my old maf in the box. email me a [email protected] (I got the email address when I was fixing up a 67 VW split window bus, like 15-20 years ago) let me know and i'll look for it
