i have a 1977 safari toptank. i have the fork measurements at home, not with me at work unfortunately.(frame is getting painted so the headtube size isn't accessible right now)
but i can post em tomorrow. been riding bent forks for too long, they recently completely exploded oil everywhere....they're just toast. the fork tube caps are totally dry rotted, dunzo..
i wanted ebrs but would prefer some with fender mounts. the OG front fender has an awesome little fin on it that has the safari zebra striped decal
