What about these Bill?? I thought these were the factory pants for a 71 model until the "blunt" ones you show on 21V came into use.
Seems there are three types eh?
Brian best described the differences in a previous post:
There are four distinct versions of wheel pants, all take different mounting plates. The ones in your photo are for the flat gear, 1968 and earlier, these are "tuna" shaped. The 1969-70 had a different style as shown on the attached early Aerobat photo, then there are the 1971-73 type that I have on my plane- these have distinctive "flats" over the top curve, and all 1974 and up are the rounded current style most Cessna's have.
I have an extra set of the 71-73 style I will be selling soon.
You can put the newest style on any tube gear 150/152 so long as you have the matching mounting plate. I've seen the newest style on the earlier tube gear planes, as some owners like the little door for the valve stem, the ability to have a brake cuff fairing, or they were simply the only set-up they had available......................................................I'll differ with Brian slightly about backing plates.
There are five models of wheel pants. 1959 to 1965, which use their own unique brackets. 1966-1968, 1969-1970 appear to have the same backing plate. 1971-1973 have a different plate, which is the same as the 1966-1970 plate, with the exception of a notch cut out of the center for installation on the tube gear. So, the 1971-1973 backing plate should fit all prior year of pants and gear to 1966. 1974 and newer pants have an unique backing plate that will only fit that style of pant. Though this plate should fit all prior year model gear to 1966.
So, for example. To fit the pre 1968 pants, like we have presently. To our 1975 airplane. I will use the backing plate from a 1971-1973 model. Clear as mud now?
