Hi ,
My suggestion is to forget trying to learn how to do something that
only May fix your car .Pay an expert in the field and go on .
I'm preaching to the choir ,since I'm in business working on all Datsun /
Nissans
:-) .
Do you know how many times we see people that assume one thing ,
when the repairs may revolve around something different ?
Good Luck !
