I was wondering is i can use the hardline for the a/c as a conduit to run wires from the engien bay to the dash instead of finding a place to drill a hole and get a plug and all that stuff? if I can what do i need to do it? and p.s. i removed most the a/c all thats left is the hard line through the fire wall and the condencer

This is a feeler post to see if there's any interest. Want to see if I can get enough people to commit to the major parts. Like turbo,header and waste gate...Complete Head...AEM EMS with custom wiring harness all the sensors(MAP,O2,Coolant temp,Air intake,crank,cam,knock and boost) and complete MPI...Seats....Chrome Dipped SHP rims with good tires.....Intercooler and piping with spray bar,plumbing and nitrous bottle...   The T56 with performance rebuild transmission,adapter plate,fidanza flywhee

Kinda garage days right now I recorded this with my iphone  

Can anyone advise/confirm if a nissan r180 clutch pack fits a big diff or any other make of LSD clutch pack or if and where I can get genuine M/bishi parts ?? Idealy I would like a Torsen but unable to find any info for our cars.
