61 valiant/lancer filler tube ?

I measured a '62 passenger car neck and it came out 22" with the tape against the backside of the retaining ring and measuring along the top of the main tube (as installed) which would make a '61 23" approx? Measured the damaged '66 Barracuda fill tube and it's about .020" larger on the OD but measures 24". Did not have a '61 for comparative measurements. Wanted to let you know my '66 neck is longer also and could possibly be easier to find than the '60-'61 fill tube your looking for.
