I'm going to add capacity for 20 gallons, that'll give me an ok range.

The back wheels are my original wheels that needed spacers to fit. After putting the 280zx struts and hub on those wheels didn't fit at all on the front. I think they needed like 3 inches backspacing to not hit the brakes. As is the 280zx wheels need 3/8" to clear the brakes, but if you use the OEM brakes that may not be an issue. the oem brakes are 3x more than you need and the wilwood calipers probably put you up to 4x more brakes than you need.

It took me about 2 years to get the struts on my car from when i bought them. But there weren't as many easily available parts, there are at least 4 sources for the coilover kit now, before maybe 1 or 2 mostly in AU.

I'm working on a sort of "hotrod your datsun 210" book like the ones for z cars, so I'm collecting info heavily at the moment.
