Radiator hoses for '79 24' MH

I am replacing all the hoses on my 1979 24' MH. I understand from searching this site that they are hard to find. The upper hose on my MH now is GM 6259953. I found that part at GM Parts direct ($17) and Rock Auto has a Goodyear part number 377 closeout price at $5.28 ( I cut 5/8" of the radiator end and 1 1/4" at the t-stat housing and it worked fine). Now the big question. Does any one know the part # for the lower hose and where I can find one?

lower radiator hose for down flow radiator

Okay got it put back together. The GM part # for the lower hose on the down flow (vertical) radiator is #343414. It has been discontinued for some time now. I looked everywhere I could think of with no luck what so ever. I took the hose to the local Auto Zone and matched it up with a hose from what I believe is for a Ford pickup. The part number is Gates # 71710. It is listed as being 1 23/32" i.d. The GM part is listed as 1 3/4" i.d. It is really tight but, it will go on. The shape is a little different but it seems to work fine.

upper radiator hose

Here are a couple pics of the upper hose I used. It is a little different shape that the GM #6259953 but it starts and ends in the right place. The end that mounts to the t-stat housing is belled and you have to cut the bell off. I cut about 3/4" off the end that mounts to the radiator as well. You can see the pieces I cut off in the first pic.
