CBF reading through the thread. Can anyone tell me; can a T56 be fitted to an early model commodore (VC) without modifying the firewall or trans tunnel in any way? The car in question is a genuine VC Brock, so the owner wants to be able to return it to original condition if ever he wanted to.

Awesome.. just checking out if I needed to do something the same for my car. Obviously not if I use the normal Charge light in the VL Dash. Good to know though if you do change to LED's! Some original photos have not been recovered yet.

What does everyone use for Accelerator Cables? The normal VL 6 cyl one is a) too long overall, and b) slack between sheath end and cable end is too much. Can get it shortened, but there must be a cable that can just bolt in? Normal VL V8? Or HSV VL Group A? Or will a VN-VS V8 one be ok?

Good to know though if you do change to LED's! yeh factory light has internal resistance, i got a pack of 30 led's for the entire dash and the rest worked a treat, did my head in for a little bit haha ---------- Post added 17-04-12 at 10:22 ---------- Quote: Originally Posted by InsaneVL [View Post] What does everyone use for Accelerator Cables?

Or HSV VL Group A? Or will a VN-VS V8 one be ok? in my rolla i just used the factory cable, works perfect the factory cable though i did the following on my aftermarket plenum fit the sheathing first and make sure it's the length you want (do this without the cable inside) once you have that cut to length fit the cable in the throttle end and run the excess wire through the pedal, depending how much longer your cable is you might have 10mm or 100mm excess market it with a texter and pull the whole lot out i drilled out the old stop and solder it back on in the place i wanted it, then i crimped the fitting and never had a drama Some original photos have not been recovered yet.

Good news though is I don't need the crank / stall spacers as I'm getting a custom stall made up anyway. Just the bellhousing spacer, starter motor and brackets. old post i know but you could just push the engine through the fire wall until you clear the starter Some original photos have not been recovered yet.

How the hell do you solder them? surely not with your usual ****ty 240W soldering iron? Need anything special to Crimp them? ---------- Post added 17-04-12 at 21:21 ---------- Quote: Originally Posted by RB-GEM [View Post] From what I've read a vx v8 one should do the job .
