sounds good with the fan
BVVC about the length of the mounting to clutch there are short and long
you can space out a short one but long one might hit your radiator with the center of the clutch
measure your water pump hub to radiator (just rough is ok) and take it with you
tight fit on my 68 dodge 318 but I had a 440 radiator
measure your fan
I think 6 blades was about it on early motors
what's this clutch/ fan off of?
3/8 connections are fine for a TF I use 1/2 for OD
sound about right- have you priced a new one?
