It' been a few years since I tried, but if memory serves...I had tried a 24F in my SMOG 289 car, and yes, the tray is shorter, but I believe it hit the filter can, causing me to take it off (as a matter of fact..it's STILL OFF, though I've seen it in my bucket of spare parts) Maybe I could strap it (smog pump filter can) back on and test fit a group 24 again to see things for myself, then possibly pick up a 24F tray if it actually clears it I was looking this afternoon for pictures of a group 24 in a 67 with smog and did find one pictured. (filter canister was really close) That photo also had the radiator support cut out to fit that battery in there, thats surely not going to happen
On edit, I had a date-code correct 22F tray but upgraded to a 24F tray for consistency to the AC option
