Hi all,
I am putting a new foam kit into a 66 GT350 heater box. I am having trouble getting the two halves of the heater box to seat into each other to install the clips. I even removed a section of foam on the sheet metal internal flow control assembly, to get it to seat flush on the heater box. I feel the foam is too stiff and is not crushing like it should. Or it is too thick or both. Has anyone else had this issue? Is there a better kit out there that better matches OEM?
I just checked the NPD kit and it says:
GASKET SET 18A569-1C, Heater Box, repro, kit includes some components that are made of a more correct open cell foam that is much more compressible than the other kits, The cowl seal is not as nice and users may want to consider the 18A569-1 heater inlet to cowl gasket separately, Includes gaskets for both side and top hinge doors.
Any body try this kit?
Thanks
Cory
