#689 Hertz dog legged traction bars with rubber pads over traction bars, no boots. When did they switch from rubber pads to boots on traction bars? I restored #731 years ago and it had boots on traction bars.
This is not comprehensive by any means, but it’s what I’ve gathered over the years.
As far as I can tell, all the carryovers got seals made from inner tube rubber with a slit in it, covered up by fiberglass boxes. With the possible exception of the 4 factory drag race cars. I don’t have good data on them.
After that:
253 – fiberglass boxes
269 – rubber boots
280 – rubber boots
285 – rubber boots
341 – rubber boots
389 – rubber boots
429 – rubber boots
477 – rubber boots
554 – rubber boots
584 – rubber boots
671 – rubber boots
689 – “rubber pads”
731 – rubber boots
744 – fiberglass boxes
754 – rubber boots
796 – rubber boots
914 – fiberglass boxes
As always, the info for each car above could be wrong. I just documented what I was told or happened to find reported – sometimes here on the forum under other topics.
I know that listing “fiberglass boxes” without mentioning what was under them is not optimum, but that’s what I’ve got so that’s what I put on this list.
I'm guessing Jeff Speegle has more and better data on this topic. Maybe he'll chime in.
