Sure, you could mount it in the cubby hole, believe somebody sells a kit for that somewhere.
Or, you could utilize the brackets that the manufacturer sends with the gauges and mount them under the dash. Most of us prefer to have them somewhere we can read them easily while on the road, thus we're using the A-Pillar pod from Autometer.
Some guys have mounted the FP gauge under the dash with the man. bracket since that one doesn't need to be read constantly, and use the steering column mount for a dual-gauge (i. e. boost/egt combo). However, that would necessitate buying the steering column mount and you're trying not to spend the $$.
Best idea yet, cruise the classifieds, many guys selling gauges and/or mounts as they change or upgrade their existing setups and you could pick the gauges up on the cheap, thus saving you enough $$ to justify spending the $50 on the pillar pod setup.
