Little off-topic, but apart from a 4BT swap in my Willys MB on M38 drivetrain mutt, this is maybe the next best thing?
Also, go on YouTube - Broadcast Yourself. and search for "Splinter Jeep" to hear it running (3 different videos).
Since I have an aftermarket 3. 6 low-range gears in my Spicer 18 T-Case, I would just need that VW to T90 transmission adapter. . . with 5. 38 axles and 3. 34 1st, I already have a 65:1 crawl ratio.
