workhorse 2004 8.1 help please...Radiator hoses...

Realized after my 2004 Southwind / Workhorse threw a Serp-Belt. that I had better replace the typical Maintenance items. FYI, your repair contract does not cover maintenance items. Anyway, i was successful at getting the right tensioner and idler pully, belt. But the Radiator hoses, upper, lower, bypass are proving very difficult. Been all over the internet for hours.
Old hoses have the following numbers on them, which are NO help, so far:
Both say Made in USA.
Lower : 3C24 EBP D1 80MH44 XBS 1305 LS
Upper: 3B28 EBP D1 80MH25 XBS
