Cobraman,
Absolutely do-able but, it is not just the steering wheel involved. You need to know where and how to mount the sensors, putting in a passenger air is just as do-able. Definitely not you average type car guy job. Use a real pro for mounting and hooking up. I do think side impact bags may quite a challenge but could probably be made to work too.
I've had guys try to put them into street-rods and set them off almost every time by not knowing the wiring or the order they need to be wired.

Ps. Testing is the real chore-to test and NOT to set off is the goal!
