Re: 71 GMC engine swap-arino

Ok guys... Anyone know of a working upper radiator hose? And Water neck? The original hose is about 4 inches too short and rubs on the side of the CS144 ( A CS144 off a 2000 Escalde works with 5/16 2-3/4,long grade 8 bolt in the passenger side bolt hole fits perfectly. Might want to get a 1 inch longer serpentine too). The original water neck points directly at the Alternator and the replacement I bought points to the driver's side, up at a135 degree angle and forward about 10 degrees so if I had an original hose(Dayco 70935) that was about 4 inches longer it would work fine... Any suggestions are appreciated. I'm currently looking at Napa hoses 7575 or 7595.
