Jack's Comments:

This kit is all you need to mount the heater box to the firewall. Comes with the correct mastic washer to seal the nut to firewall. The zinc flange stamped nut and mastic washer to are exactly like the production hardware. Made in USA

Concours Notes:
It was common that the nuts could be fully or partially covered with the spray sealant (also called adhesive in the assemble manuals) appleid at the factory in both years. 1969 and 1970 had different sealant applications specified in the assembly manuals and each factory also applied the sealants/adhesives a little different so do your research before application.
