Space saver

[6bblgt]

I think that's still a 5.5" rim for '71 - unclear stamp

the space savers had a "recall" to install a safety overpressure relief valve, I think they got the yellow sticker at the same time

Correction on something I stated earlier.  My space saver says replaces 7.75, not 7.78. My eyesight is getting worse as I found out trying to read it on one of my tires stashed away in the house last night!

Dan, do you have any estimate of when the change in the sidewall marking occurred from 7.75x14 to F78-14 replaces 7.75X14?
