75 series suspension and lift

[Bucky 75 cruiser]

G'day guys, I'm looking at going all out on my 75 series landcruiser I was wondering if anyone had a suggestion or knew how to get 37" tyres or preferably 38.5" tyres under it, currently im thinking of doing a 80 series chassis swap or doing a coil conversion with 79 series axles but still can't find a lift big enough to do so.
Any input is appreciated thanks

Lift doesnt help with tyre clearance. Flex it up and cut away everything that is in the way, usually the front guards etc. Even with good leaf spring front flex the factory 31'' hit the guards hard.

Other option is limit up travel and or huge body lift.
