Having Trouble Forte rear end and upper arm mounts

[Snowdak]

Help! Ran into my first snag on my new build. Ordered a rear end from Mike Forte, tried to mount the two parts of the upper arm mount they do not seem to be even close to the right diameter nor does the stabilizer bar seem to hit the pumpkin near the mounting hole. Tried to muscle the two halves with longer bolts and impact wrench and looked to be stressing welds. Any suggestions?? Also diff cover does not fit the diff very well in spots but covered the gasket.
