A little background to my van, its a 1988 Super Carry, 135,000kms, 4 speed (i know

Firstly, ive been reading around and cant find a good answer on how to lower my van (ST90)
Rears are lowering blocks, but fronts are springs
Does anyone know what springs would suit?
I believe the MB uses Swift SA springs to lower it 2" (read on this forum)
Are MB and Carry struts the same?
Im keen to get some sort of aftermarket carby/weber setup, but unsure of what will work and im not too keen to be the guinea pig! Ill be sticking to carby setup (too much stuffing around going EFI)
Would love a quad throttle body but couldnt really find any threads on here where people have actually got one working
Anyone have anything that has been tried and tested?, and preferbaly something easy to setup (I can weld up a manifold if need be, thats about the most work I want to be doing)
Im a noob at carbys so bear with me if i say something stupid
Step 1: Rims and lower
Step 2: Headers and full 1.5" twin exhaust system
Step 3: Intake and carby
Step 4: Tune and dyno run!
Cheers guys
