I am just back on the road after deploying my airbags...I had my body shop put in "used" but certified airbags and replace the module as well as clockspring and put a new windsheild in. The total for all the work was 3460.00...on my 98.
The 99+ models have seat belt pretensioners as well as two sensors in the front fenders. I would recommend e-bay the airbags from a reputable source and pay the body shop an install for you. This should keep the price down probably total for 1500-2000. If you do not care about re-sale (like me) and will probably drive it into the ground just put an aftermarket steering wheel on it put the cover over the passenger dash and move on. I replaced my airbags and stuff since my now 13yr old will be driving it soon and I could not live with myself if she got hurt when it was something I could have simply fixed.
The other option would be to find a gently used one for your 6g and start over...take off what you can and move on they are never the same after a wreck like that. I was fortunate mine was mostly cosmettic since I deployed while pulling out a stump...
