Back in the day Group C racing one of the tricks to get the Holden Torana to handle nice and be more predictable in corners was to fit a rear pan hard bar to give much better diff locating than the OEM triangulated 4 bars offered.  However the body, subframe and floor pan at the rear is no where near strong enoungh to concentrate the loads of pan hard bar in any one spot, so it has to be carefully planned and constructed, especially so in a street car like this that we cannot put a full roll cage in. You see in a race car I can place the roll cage in a position to pick up such loads placed on the pan hard bar brackets, but in this situaton we couldn't. The picture above is with the unit installed, keep in mind the car was just a shell so no weight was in it and the rear is sitting high. Once the full wieght of the car is on, it will sit fairly level.  It retains the original triangulated 4 bars however we run PU bushes in the bottom arms and ordinary rubber in the top arms. So the lower arms and pan hard bar do the locating and the top arms have some give so they don't bind with the pan hard bar.

Shown here is me developing a carby linkage set up for our AussieSpeed tunnel rams for a Holden 253 - 308 V8 engine. With the carbs mounted east west it gives better clearance at the back of the motor, however it makes the carburettor link more difficuilt.  This kit has come up a treat though and will take most OEM stock throttle cables and kick down cable accessories with slight or no modifications.

A common issue with the older speed boats from the 70's and 80's is that the alloy exhaust heat exchanger manifolds, commonly called marine manifiolds, are quite often rusted through and very thin.  This effectively leaks water too close to the exhaust ports and there is a danger of too much water entering the exaust valve and into the cylinder, which can terminate engine parts.  Here I have fitted our new AussieSpeed marine manifolds to a 308 Holden V8 whihc is sitting in a Flycraft clika ski boat.  I was able to rewok the stainless steel pipes to suit.  I can make new pipes too if need be.
