You ought to pm mach4 and ask what size Hose was used.
The only Vehicle there is extensive stuff on 617.952s Oil Cooler Hoses but not on the other Engines. You did not say what you planed to do the job on.
I believe the original size of the Oil Cooler Hose is 15mm ID buy The colsest US size is 5/8" ID and 5/8" is a little loose.
There is at least 3 long threads on the Oil Cooler Hose replacement.
