Bought it a present...
An NP241 planetary doubler off pirate. Not really a doubler since its 2.7:1 but...
Now I have a late NV4500 trans, (soon to have unless I get burned) doubler, NP205. All 32 spline.
I was working on an NP203/NP205 doubler and found that the NP241/NP205 setup was cheaper, easier, probably shorter and certainly weighs less, plus it's clockable to tck the 205 up out of the way.
I figured since a PO had scrapped the original 205 for a 208 for better gearing, I'd solve that problem for good. Also since I need to get the driveshafts cut, why not do it right the first time...

I parted a Suburban to get the round pattern NP205 and made about $700 so $650 for the doubler is painful, but I talked myself into it. Not too difficult.
