ok i found a dayco hose for the upper radiator hose that works. its a little big in diameter but i tightened it down good and put double clamps on it just to be safe. seems to be just fine. so for the upper radiator hose on a 1982 310 turbo diesel its a DAYCO 70448. the belts for the alternator are SPB 1250. i got mine from Vbelt global supply. they are metric measurements 17mm across the top, 13mm deep, and 1250mm long. i tried the spb 1200 and they will work but they are a bit short and were hard to get on so i will go with the 1250 next time.
