Also got those windows in! Will probably have to re-install them, i couldn't get them flush since the panel is curved and was afraid to bend the 40 year old bubbles. May just try and find some rubber trim, so they look flush.
Thanks for the tip, will try and find some of that stuff locally here. After removing the soaked front shag, I rolled up as much of the back carpet as I could. After a few days of letting it air out, I'd say most of the funk is gone. I haven't scrubbed down the bare floor yet as I'm still deciding on how to put in some new carpet. Going to swing by an upholstery shop next week to see what they'll charge, maybe see if they can fix the droopy headliner too. If it's crazy $$$, then I'll just get a mechanic to help me undo the bolts from the bottom of the van and install a pre-cut kit myself.
I got the weather stripping that was leaking replaced too, so we'll see how that goes over the weekend, supposed to get some rain over the next couple of days.
I've rebuilt Chevy columns on 67-72 trucks, but they are somewhat easy to find the parts for. YES absolutely get something in there, without a bearing for support, you will eventually wear the column down and it will snap the shaft. How do I know this? It's happened to me before.
In my case I was driving the truck to my hunting camp, I had literally just pulled off the main road which was 55 and into the parking spot 2 minutes up the trail when the shaft snapped and I had no control. 2 minutes earlier and I would have probably been upside down in the creek. I had to rebuild that one in the middle of the woods on the bed and tailgate.
If you can't source a good bearing somewhere, try the truck columns. I would think the poly would work in a pinch, but I would feel more comfortable with an actual bearing. My one tip is lay the parts out in order when you take them out, so it's easy to install them in reverse order. Good luck man.
My son has an orchard on his property, lots of apple trees, peach trees, plum, and pear. He purchased the property about 12 years ago, the previous owners had a roadside fruit stand for many years there. Besides enjoying the harvest in the Fall, we like watching the deer and bear raiding the snacks all summer long.
