thanks for the info . i didn't know if plugging off the fittings would cuase back pressure or some other restriction or problems

I doubt that you can just block them off. Go to your friendly GM dealer and find out for sure. Try a wrecker for a housing that isn't for an external cooler. Also check your housing for a bypass valve, if there is one just pull the guts out of it and plug the holes off then. That way the oil will flow with no restriction. Or,you could run a separate cooler up in front of the rad.
