Which wrecker did you give the ute to so i can have a look. (Sydney Right).

www.ozdat.com there are a few tailshafts this week (search driveshaft, prop shaft... all the possible names) but i dont know what will fit.
My old CA18DET ute project had a V8 falcon shaft cut down and modded with comodorre uni's.
And my current ute CA18DE has i believe a STD H165 tailshaft but i have written down in my book when i bought it that the uni joints are 'Same as early holden RUJ1786'-maybe these are stronger than STD???
Dont know much about computers but a few years ago there were only 2 people in Syd that could wire them up, one being a rotor house, called redline rotary in brookvale. this number may have increased by now.
Not sure what your trying to describe but this manifold thingy is or was it where a wastegate was?? And no CA's never came TT.
Also do you have any parts you want to offload??
if so let me know
Cheers Henry
