I had this ~70L tank made for a guy who never bought it. My cost was $400, selling for the same plus shipping. It bolts directly into the holes for rear sway bar bolts, but bolt holes must be drilled. There are four threaded fittings for hoses (pickup, return, vent, drain, or what have you) and one large threaded hole for filler hose. It would be handy to drill for fuel gauge sender, which are universal. I have the same tank in my van, but at 120 litres. I've got a lift so there is more room, and I've been known to go on long road trips.
I haven't been posting on this forum for years, but some of the veterans might vouch for me as honest.
Here is an example of the tank installation:
