91 burb parts interchange and swaps advice

[Smogmonster]

ok so im looking underneath swapping in another steering box and i can see i have several bad bushes so its a case of the may aswell while im here scenario.

so i was at a friends yard and he has a gas burb down there 4x4 but it has regular bend smiley not frowny front diesel leafs like mine so would it be a good idea to fit those to mine? and maybe add a leaf from some old rears i have here? il have to remove them and buy them and maybe re bush them so..... first up

who has the best deals on bush kits? and would you buy these used springs or just buy new and be done with it and who would you buy from?

i only want maybe 1 -2 inch of lift over o.e simply due to the added weight up front
