the reason the cross member is so low is my driveshaft angle is so much or was it is 20 degrees now thats where i like it the shaft is 1410 series joints and they say it can run a 35 degrees but last summer it was at 30 degrees and the center barring wore out and broke as i was towing my boat not fun so this time around i set it low (engine trany transcase) to keep the drive shaft straighter and i elongated the wheelbase. its still got two feet ground cleance and it keeps the center of gravity low its got 1 1/2 springs and a spring over so its about 7 1/2 inch lift total.

Steve to answer your question on the added T-case support, yes you will need it. GM, Ford and Dodge all used an extra support on the married 205 t-cases. It is just too heavy for the tail housing to support alone.
On that last picture of your rear drive shaft, is it just me or is your pinion angle way out of alignment. It looks in the picture like it is pointing higher than the t-case.

ill have to add something for the extra support. and good eye the angle is out the pearches where welded on from my old setup with the chevy 350 i dont want to cut the pearches off and reweld them so im going to add some shims maybe 2*-4* should do it steal of course with the pin that goes through them and the leaf pack i didnt want to address them until the cross member and the rear axle (streched) and the weight of the tub were finished

jeep

i got my jeep on the road after a year. i ran my gears and tires and i think it was like 1800 rpms at 60mph but just driving normal 1st gear is the usual low gear quick understandable 5.56 but second is almost not worth useing and 3rd feels like its reving to much i shift into 4th and it bogs down until i get to the end of the gear and shift into 5th and again bogs down until the end of the gear i have a nv4500 and a np205 and 4.10 gears with 37inch tires they have worn a little. maybe i got the wrong gears i dont know i dont want to loses my crawl ratio but i need it to be drivable i may not be taching it out enough because it sounds so loud. any input would help maybe someone has this setup
