    Is there a gear reduction starter available for my m1008 with a 6.2??? I have already converted the wiring to 12v from 24v.

    Yes, it's the 28MT found on newer 6.2's and 6.5's. Pretty much a straight bolt in deal, but you'll need to either mod the current starter nose brace or source the correct one from GM for the 28MT.

    So whats the difference between the 27t and 28t? I have found both, but would like to know the difference. They listed the 28t for a manual transmission, and a 27t for an automatic.???I am confused.

    I ran the 28MT in an 700R4 truck. Greatly improved starting, especially when the motor was warm, and on very cold starts in the winter.

    Rene,

    Is this brace the one mounted on the rear of the starter? Just checking since I have a gear reduction starter arriving tomorrow and didn't know anything about a modification.

    The brace goes on the front of the starter. You can make one out of some scrap angle iron.

    i guess it's the rear of the starter...it's attached to the end that isn't plugged into the bellhousing.

    Thanks for the replies. I had planned on redrilling the support, but wasn't too sure if that was the only modification after reading the initial posts.

    I swapped the factory starter on my '84 C20 with 6.2 and 700R4 for a 28MT. The factory brace bolted right back on. Also, I've had experience with the Powermaster 6.2 starter. I do believe it spins the motor almost fast enough to drive. Still, good battery cables and good connections on both ends seem to make as much difference as the 27-28 MT swap.
