[SCOTI]

The ECE x-member is in a 'stock' location as in I was able to utilize factory holes in the frame rails for the mount hardware. The total height of the trans spacer is 3.5" which includes a 3" block, a .250" trans mount spacer, & a .250" shim to dial in the exact height I want.

I recall Nathan saying the motor is moved up about 2" & forward about 1.5" w/the Dropmember/sbc combo. He also recommended setting the trans @ 5° down. A 2pc driveline would mean no cab cutting; 1pc driveline = clearancing req'd (less clearancing needed on 6x-66's vs. 67-72's).

With the 2pc driveline set-up per Nathan's recommendations, it would work. Even though it would work, it would not be ideal (there in lies the catch-22; we're dealing w/extreme drops & their subsequent extreme angles). There's no achieving 'perfect world' angles w/these extreme drops. That being said, I priced a 2pc driveline from 2 different sources & the quotes were $600-700 (price included new yolk, balanced front shaft, balanced rear shaft, 1310 F/R u-joints, HD carrier bearing, & CV or slip joint (w/warranty).

At $600+ bucks for a functional compromise, I decided to spend much less, trim the cab, & have the same functional compromise. I also planned for a fail-safe. If my angles don't work, I can drop the trans a little more, use a CV joint, raise the pinion to near zero & Nathan says I'll be good to go. The 1pc/CV set-up also fits under my raised d.shaft hoop.

Also.... If I would have left my rear wheel C/L alone (instead of moving it back 1" to center it within the wheel-well), I wouldn't have to do anything to the current d.shaft I used for mock-up. I have another d.shaft that's slightly longer & will have it cut down to the necessary length.
