paint cost me £100 ish in total (I have pm'd details of what i got)
Powdercoating cost me £80 cash but i did have two extra wishbones done and sold them for £70 on ebay so that basically paid for itself.
Zinc plating of nuts and bolts/brackets/gearshift selectors and fuel lines was £40
Various other items i.e clips/brake pipes etc cost about £35/£40
The fuel pump carrier was £115 (expensive but well worth it) plus about another £100 on various odds and sods - braided hoses etc etc but obviously you may not want to take it that far
