Is it common for the mounting feet on the 2 adapters to be different heights? I never noticed before but my doubler adapter feet are a good 2" lower than the stock adapter feet, I always assumed they were the same.

ORD Doubler feet vs OE adapter feet height

Am I the only cool kid with a Doubler? 
What adapter are you using?
It's an ORD Gen II billet adapter (2"up rotation).
4spd w/ 10 spline OE adapter to Doubler.
If it matters I've got an '87 frame and a flat type crossmember from an '80 K10.
As it sits the crossmember is on the OE adapter bolted directly to the frame and the Doubler feet are almost even with the bottom of the crossmember.
Could that be because the drivetrain slopes downhill?
I guess it could but I'm assuming 
it's where it should be because I'm using ORD engine mounts and fairly new t-case mounts. All of the mounts are several years old but virtually zero miles and no wheeling or hot rodding that might have stressed them.

You know, I guess it could be sloping. I always figured that, even with the frame and crossmember differences, the feet would always be in the same spot.
I wish I would have found this before welding the axle perches.
If I have set it up on a slope, will it hurt anything? It's not much maybe 1.5 @ the Doubler adapter.

Factory drivetrains typically slope down 4-5 degrees, it definitely doesn't hurt anything.
Welp, looks like I should have paid more attention earlier on. Thanks for talking this out with me Chris, I'll figure out a spacer or something for the second crossmember.
Well, mine's a TH350 and NP203, so different than yours, but yeah, the doubler foot is down some... compare tranny (left crossmember) to doubler (second crossmember) here:
You'll notice it's sloped as well. I just welded up some flat stock into appropriately sized spacers, then drilled through them from the flat side and they came out fine.

Yea I got a th400/ ford 205 adapter to mate the 203 to my th400 in my bent up frame. It took some 2x4 square tubeing to make it work in my k5.
The factory mounts drivetrains on a 4-5 degree angle so the carb will sit level. It also helps keep the oil in the rear of the pan. A carb manifold is angled forward to compensate for the rear slope.
If you look at my build pic you can see the carb base on the manifold is not level, cause I wanted the flattest bottom I could get. This can make for tuning issues with a gas carb if its not sitting level. I'm running propane so I could care less.
