Thanks for the inputs guys.
I had a nasty experience about 10 years ago on a 46 Ford where a nearly new oil line to the filter split spraying half the contents of the sump around under the bonnet so i am tempted to leave the filter off. But many of the repro Ford parts are rubbish, hoping the Chevy stuff is better, certainly the parts i have ordered so far seem to be US made, most of the Ford stuff seems to be from China.
Will drop the sump to see how much crap is in there first.
I am travelling to the US in a week and will try to get to the Brothers Truck show in Anaheim hopefully pick up a sump gasket set but will see what the repro Chevy oil lines look like.
