Love that 'Burb! That's really good you got the top all caught up with. That's one thing that drove me nuts about my old friend and his panel he set on a Suburban K/10 chassis. A '67 California body with surface rust on the top. I mean the whole top had the paint burned thin. Kept (keeps) it outside and as each year went by, "I need to take care of that surface rust". I'd agree and say "When are we going to do it?". All that work, including the expense of having a '72 NP205 converted to run a 700r4, and that top just kept rusting.
Ooooh.... N.O.S. K/20 parts. My favorite! That's one thing I hold dearly. I get people bugging me to sell things they learn I have. My standard reply is "Sorry, I don't see K/20 parts"
