I'm in the same boat with an old set of skyline towers. I have what was known as a 'stornco adapter' that was machined by some dude for FJ cruisers to make them fit. I was thinking about messing around with it and seeing if I could get lucky and use the same adapter for my Taco + the skyline...
I haven't had a chance to test drive yet. I'm wondering how the interior feels compared to the FJ, I'm assuming it's significantly less roomy, but curious about how much so.
