power ateering box install

[wwdd77]

Ok. I know about the plates u can buy to make the conversion, and if thats all it was, id buy them.
Pancaked xmember 1.5" and want to raise the steering box up the same to alleviate any bump steer.
Its off a 1900 suburban, so im making a template from the old frame section for hole patterns.

Any suggestions for this?
