Reading my mind. Planning on checking the local yards tomorrow. Been researching all the gearing info this morning. The fun part will be finding a 4x4 V6 auto (the 4x4 part=fun) around here.
Need to tackle an exhaust manifold leak today... hoping a bolt isnt sheard off........
Unfortunately, I dont understand the bit about the axle disconnect tube...? Info or pics on what you are referring to?
The 90's trucks had fixed hubs and an vacuum operated disconnect on the Dif. It can be swapped with the driver-side tube off your diff.
Is yours missing the bracket that bolts the down tube to the bell housing? The exhaust flexing will be a continuous problem with blowing out the down pipe gaskets. If it is missing the bracket get one ordered.
I plan to put a flex pipe on mine in front of the CAT to give a little flex.
The other problem is the threads stripping on head, again that missing bracket contributes. With a 90 deg drill there is Plenty of room to Helicoil all but the very last one up by the fire wall if you find the studs pulled free. Pep Girls has a kit in stock for $30 if you have them in your area.
