Re: 73 Wagoneer running gear
A '77 will have Dana 44's front and rear with either 3.07:1 ratio or optional 3.54:1, (better). Since you say it has full time hubs, then it's got a TH-400 automatic followed by a Warner Quadra Trac transfer case. Low range was optional on Q-tracs, so check the floor in front of driver's seat just inside of the hump for a small lever. If you have it, then you've got 2.57:1 low range, if not then no low range, but a Q-trac with low range could be swapped in. Milemarker has a part time conversion kit with or without 16% overdrive. I'd get the one w/o the o.d. to avoid from changing the gearing. 4WD Hardware, (800-333-5535), has these kits. The kit w/o o.d. doesn't come with a chain, so it'd be a good time to order and change as they are good for appx. 60,000 miles. When converted, xfer is then filled with ATF, rather than special Q-trac fluid. Check the side of the engine block to see if it's got a rare AMC 401 V-8 engine. The displacement is cast on the side, should be either a 2 bbl 360, 4 bbl 360 or 4 bbl 401. If 401, then you've got quite a find.
