After exhausting all sources for replacement window seals, I have visited with Kip Motors (http://www.kipmotor....lded-rubber.htm) about reproducing sets for us Datsun owners. I have personally seen the vast array of window seals that Kip has duplicated. It is possible that one of their channel molds duplicates the 520/521 wing window seal straight pieces. However, it may be necessary to mold the three corners to properly assemble a replacement.
The part numbers I am intending for reproduction are 80241-B3000 and 80242-B3000 for the 03/1965-09/1969 Datsun 520 & 521.
In order to proceed on this project, we need a sample pair of original wing window seals. It does not matter if the seals are torn or have dry rot. We need a pair that has complete corner radius and a cross section that represents the glass thickness. These samples may be destroyed during Kip’s analysis of the feasibility and cost of the project.
If anyone has an old set they can give up for this project, please PM me and we can make arrangements to go forward with this.
Thanks,
Keith
