Hey all you aussie guys

I need as much info as i can get on shops that sell parts to swap the manual gearbox on the rb26 to an american automatic. Im having lots of problems keeping ujoints in on piece with my current setup. Id like to go auto for drag racing purposes and i think and moderate stall will be easier on the rear end then a clutch. any info is much appreciated and mayber one of these days ill get the rb26Z down the strip in one piece and in less then 10 sec ;>
