Brent,
When I recently replaced my oil cooler lines with JR Slatten's parts, I
first thought that all I needed would be the flexible hose parts.
However, after I got the lines off---including the solid tubing parts
that connect to the oil filter adapter--- I found small but deep
corrosion pits in the line the closest to the exhaust manifold. The
pits were on the the tube's backside and were not readily visible before
I had them off in my hands for inspection. Needless to say I end up
replacing everything between the oil filter and radiator. You might want
to inspect your tubing carefully while or before installing just the
flexible hoses. Good luck.
