hi

assome of you may know i recently got a 95 lwb vitara and am digging it alot.
ive got a few questions regarding it and thought id put them all in one thread, thanks for your time.
1. ive got 30X9.5 tyres on 15" sunnies with 0 offset, will 25 mm wheel spacers help clearance or make it worse? or not make a difference? (im going to be running 40 mm suspension lift and will cut guards accordingly)
2. is it relativedly feasable to cut and shut a hilux bullbar to fit my car? (wondering about hilux ones because they seem to be the easiest to come by seconds hand on ebay and such)
3. I would like to carry a jerry can of fuel on the back, but dont really wanna buy or make a whole rear bar carrier thing, have i got any other options though?
4. Exhaust system. where can i get extractors from? will a new exhaust system make any power difference at all? i dont want loudness or anything so if it didnt do anything i wouldnt bother doing it.
5. Would you buy
these, or should i get second hand real ones to replace my auto locking ones?
6. to replace my alloy front diff, do i basically need to buy a whole gv front diff and put the guts from my diff inside it? or what ?
7. my suspension feels kind of sloppy i think maybe some suspension bushes are worn out, where is the best place to get a set of replacement bushes? im thinking prob peddars but just thought id ask incase there is somewhere cheaper/ better.
8. i can hear wind coming in my window when its closed when driving at like 90 and up, where can i get a new door/ window seal, or is there some other way to fix it? water doesnt get in or anything but its quite loud at 110 its only on the drivers side.
thanks alot guys, any thoughts and opinions are welcome also
