Longbox: 87 and older 4x4? Cool! There's a bunch of those around. Great info on the sizing. I've printed it out for future reference.
Tramp: 10-4 on the freebies.
Tiny: I'll keep checking ebay
rdavid: Good idea! Thanks.
I did find a place that said they had some baby moon wheels for me for $79 a piece that "should work" but they need to see the truck first. After its back from its brake job, I'll swing it by and see what they say.
