That's actually a gripe of mine how guys post a Craigslist ad link without anything else, causing frustration for folks later on who want to see what was in the ad. So, I've lodged a gripe against myself with a fine of $100 and a week's worth of community service work.
Ha! I've saved the two CL ads that I've ever seen for a 4x4 GT conversion for just this reason, they're uh ... somewhere. Looks like sambot has one of them, or maybe there are others? GTs have the popup on an astro body.
Meanwhile, I did a quick zip of the description and a few other key words in hopes of finding one of those other ad places that accidentally save Craigslist ad material longer than Craigslist does, the best I could prompt are the first two tiny thumbnails
in this photo search.
Both of those are my pics - the first one is my current 2001 CX on an F250 4x4 (CX = hardtop on a truck body), the second was my 91 XL AWD (XL = hardtop on an astro body), now sold.
I believe the one I had in the Craigslist ad is the same one they have
in the Tiger owners' forum page here, so it looks like if you join their forum, you'll be able to see all the photos the seller either had or still has.
That guy posts the same vehicle for sale periodically, but doesn't respond to inquires - I've tried. I bet the CL ad you saw was him esp if it's in CO, guessing he still has it. You can see in that thread I asked him if it was the same (plus I emailed him), but he never replied.
There must be at least two other 4x4-converted Astro Tigers out there, since
a 2008 forum post has a couple of guys talking about theirs.
The Multiply site for Tiger owners was short lived in between the days of the Microsoft site and the Yahoo site. The
yahoo site is still active, and there's a migration now to
this site Yeah, we're all over the place.
My best guess is that if you want a true 4x4 Tiger on the astro chassis, you'll have to swap the transfer case yourself. Best info on that is on the
astrosafarivan site. I know T. Low did it on the Astrolander, he's on Expo as well as the astrosafarivans site.
Anyhow, good luck.
