Keegan, you didn't have to move your cross member to mount that 31 gallon tank, did you?

Yes, I moved it back a few extra inches but forget why. It may have been because the filler neck would have been right in the way of the body mount.

Alright so I got the dirty dingo crossmember and proceeded to paint and assemble it. There are quite a few bolts. Also I'm showing the holes that had to be drilled in the frame to mount it. Notice that you use one existing hole to mount it and one of the other holes gets very close to an existing one. Theyou do provide plates that go on the outside of the frame which I haven't installed yet.

Here is the motor installed. I used anchor 2292 motor mounts off rockauto for the frame. As for the motor side I ordered a set of IFS mounts to save some money from the dirty dingo mounts. I had to trim the tabs off the passenger side anchor mounts to allow for easier install. Since I'm running a truck pan it was very close to the crossmember as others have stated it would be. It the wording on the pan was grinder down it would allow for more clearance. I added 2 3/8" washers between the motor and IFS motors which comes out to around 1/8". I thought about making a steel plate for a spacer but the washer aren't loosing any surface area for mounting.

So the only issue I have now is the secondary transfer case mount, which I know was not standard on all blazers does not line up. The crossmember came with the frame so I know it's correct. The transfer case was a Craigslist find and came with the secondary bracket. I believe the transfer case is stamped 72 though and the rubber mounts are new. It's looks to be about an inch off. I'm not sure if I should shim up the transfer case or just not use the other mount. Any ideas?

My bracket looks like it comes down further than that (I think). Do you have the rubber mounts in between the bottom of the t-case and crossmember installed?
