I used to have one in Australia. I lifted it approx 2". Like most independent front suspensions you can't go too high without stressing out the CV joints. basically just springs and dampers.
Snorkels are a popular accessory here, the series 2 (96 onwards) one fits but overlaps the RHS indicator and you don't use one of the bolts. Requires a different template to the later model.
Being a series 1, the fuel pumps don't like sitting around, as it would have been, so keep an eye on that. Being purely mechanical it may be better in the long run once reconditioned.
How do you go getting insurance for your Delica? Because I am familiar with them and not too expensive I was considering one as a US-based vehicle.
I see them around where I live in Canada all the time (every day). I'm always tempted to get one but never quiet sure about RHD. Let me know if it becomes second nature! Good luck on the build. You should start a build thread (I'd like to follow along)!
I have a 1994 LWB, some of the best mods done was the dash pod, putting in gauges that work, also removing the plastic heater hose tees and putting in aluminium ones.
I opted for airbags in the rear keeping the standard 29" tyres for fuel economy.
