Hy bowtietim, I guess my catalogue must be way out of date my listing says 1954-62 235-261 should take P/N 1168 pre 1954 P/N 1167 those are the numbers for kits that are 12V neg. ground if you want 6V neg. ground add N6 to the part number at least thats what my out dated catalogue says, hope this helps,
