'78 450SL Cowl Drain Hose Part Number

[jaybutter]

I need to replace the Cowl drain hoses that run from the drains on either side of the HVAC blower box to the transmission tunnel. I am trying to figure out the part number. I have a partly readable number on one hose. It is something like 107 835 ?2 ?7. Can anyone provide the complete number? I would like to use original hoses but may need to use something generic.
