Good day Conversion Experts. I have a 1991 GMC TopKick with the Custom Horse Hauling Box. It has the Original Chevy 366 6.0L Gas engine with the 13 Spd Trans.

I have a 2001 7.3L with 135k on it that I would like to hook up to the Trans.

Is there a company that makes a conversion plate to bolt up the TopKick Trans to the 7.3L?

Or is there a better Trans to install behind the 7.3L than the one in the TopKick?

The 366 Engine runs great and only has 50K on it so it should be worth something to someone out there who needs one.

Thanks in advance to anyone that can help with this conversion.

 

I believe there is a company that makes the stuff for the conversions, but I can't recall the name right now.
