Trailing arm crossmember question?

[76kcfdeng]

Looking for a little advice. I am planning to use a 4" x 6" static drop from ECE. I have added a 2 1/2" notch and exhaust pass through on the crossmember. I may go 4 1/2" x 7" using a block in the back.

After looking at many builds and aftermarket crossmembers I was wondering if it would be a good idea to remove the trailing arm brackets and flip them upside down and bolt them back on, would have to drill 2 holes. Seems this would help with pinion angle and also allow a spacer in between the bracket and crossmember if the wheel base needed to be lengthened. The aftermarket crossmembers appear to have the trailing arms mounted higher and this seems like an easy way to achieve the same results without buying a new crossmember

Any thoughts on this, has anyone done it before? Will I have other clearance problems?

Thanks, Glen
