Gents: I have developed some leaks in my 78 K25. On the passenger side, it is leaking into the cab floor through the 2 heater box hose holes; and along the top/side in front of windshield under the black grate. It leaks there around the side into the large vent hole on side of cab. It is coming in under the plastic cover. Anyone had this issue and/or know the fixes? Are there any grommets or something that originally plugged the space around the hoses?
Thanks,
Marvin
