223 oil pump shaft length

[moondog13]

Hello everyone! I’m new to the forum and was wondering if anyone can send me the length of the oil pump shaft for a 223? The vehicle in question is a ‘59 F100. Thank you in advance!

According to the catalog, the 223 in the F-100 takes a Melling IS-43 which is 3.84 inches long (97.55mm).

I have an original 1963 223 oil pump drive shaft I can measure when I get home if you need it still.

Just a heads up the drive shaft is a few thousandths smaller than an Allen key. It will still work but you might lose that little bit of play that compensates for minute misalignment
