Bought a part from him today and talked for awhile and Duke is very friendly and knowledgeable. Good guy to deal with if you need any misc. powertrain parts. Good place to find stuff like an np231 input shaft when swapping from 21 to 23 spline, 231j HD chain and 6 pinion planetary upgrades.... or whatever else your looking to swap around. Most prices seem pretty reasonable for these used parts, especially when compared to prices new from A.A or JB conversions or such. If your unsure of swapping compatibility on some items, he should be able to point you in the right direction.
