Here in brazil some things are too much expensive... without any special reason.. just because are expensive...
for example.. upper bushings costs R$ 30,00 each (about 17 dollars).
As we need 4... 120,00 ... (about 68,00 dollars). Ok.. far enough.. but I building everything new.. If I make some economy.. I will have some extra money to future engine upgrade...
solution? yes.. brazilian Fiat Palio.. a compact car with front traction. this car uses only 1 upper bushing each side... moreover.. dart upper bushings do not make much effort...
Fisto mod... make bigger inner diameter.. I used my small bench drill.. I've made a test with a hand drill and works fine..
second.. inner metal tube is larger than outer tube.. cut it to make the same side...
You already have a functional cheaper bushing... But I have a problem.. I love to use washers.. I think they prevent premature parts wear (don't know if I used the right word), due metal friction.
As washers are 1,5mm each.. I have to cut more 3mm from bushings.. No problem... quiet easy (10 minutes work in each)..
well.. total cost at the end.... r$26,00... (about $14,00).. 4 bushings for less than 1.
ps: Yes.. I'm crazy and I do paint washers, nuts and so on...
