    Plenty of room under the hood, its just that the chassis rails come together more just where the engine is, so the front suspension X member can bolt up. 6" further back the chassis, and no real problems. Our later 6.0lt exhaust manifolds may have fitted, but I couldnt get hold of any.

    I am getting a complete C10 front end, and diff next week. It was part of the parts I sold with the truck when I sold it 11 years ago, and the bloke wants to have a cleanout, so am doing a trip to get it all, and some other bits.
    Just thinking that I may end up fitting the C10 running gear into my truck instead of the heavier C20 gear. Any thoughts??
    Wont really know until I get all the bits home, and have a good look at them.
    Would love to fit an IRS out of a Commodore ute(Aussie El Camino), but big job.
    1978 C20 short bed pickup, GEN111, 4L60E trans.

    Hey Ian, I know this has been a year since your last post, but what a great job you did! Like a previous guy said, you Aussie's get all the cool stuff, not to mention RHD!
    I hope you're still enjoying it!
