    I could not find any direct fit to our 6 bolt balancer.

    I originally planned to use an ATI dampner because it used the 3 bolt chevy pattern and you can use a direct fit part......but that balancer phyically wouldn't balance out right on my motor.....they would of had to add weight where there was no place to add it, went back to Romac and that issue went away.

    But for the trigger I found on from nick that was made from a sbc msd kit......they made a hub spacer that slid over the inner lip hub and still kept it centered

    I then made a bracket the mounted from the fuel pump location to hold the pickup

    With that balancer a chevy kit or the correct diameter should bolt right on.....the you will just need to fab a bracket for the pickup arm........just make sure in the end it follows the curve of the wheel so if you need to adjust timing....its not tilting the sensor too much

    This is the only thing that will fit the Buick 6 bolt balancer.

    The hole in the center of the magnet wheel has to be opened up, and the pattern has to be transfer punched onto it, and then drilled.

    Then the mounting plate for the trigger holder has to be modified, and drilled and mounted.. as on this Tomahawk..

    If your thinking this is a huge pain in the rear, your right... which is why another board member and I are working on a direct fit crank trigger kit, for mag pickup race ignition triggering, as well as for use with a hall effect sensor for EFI stuff.

    We might be able to have at least a direct fit wheel available, in early 2021, if not the whole kit.. And the wheel is really the hard part here.

    The biggest thing I think is keeping the center hub hole centered, this way the run out isn't effective....the bolt holes don't really center it as much as hold it.

    I will try to see if I have any pictures of what nick did

    So the aluminum center piece......is counter bored inside to basically slip fit over the factory style dampner......clearly the sbc center hub is slightly larger than our bbb so the trigger wheel slides over the new catering hub.......then it step down so the factory pulley.......in my case aftermarket aluminum pulley......but because there is that slight lip........see black arrow........the pulley hold the bushing adapter in place once bolted..

    I did have to modify the step a touch so my pulley would sit flush.....and I opened the center hole out so I could pass a socket through to hand turn the motor over for valve adjustment and such.

    The other change i made was a used flush headed bolts with the 45* tapper and counter sunk the bolt holes so the sensor arm couldn't rock on the bolt holes.

    I only has 3 of the 6 bolts in this picture but all 6 are used as can be seen
