Ok I have a question I have an 88 AWD Wagon that has seen its share of rust here in NJ. I need a rear sub frame. A friend of mine fabricated one a couple of years ago but its time to either retire this car or look for parts. Do I need an AWD for the Sub frame or can I just use a two wheel drive. The car is still driveable but how safe I not to sure. Thanks in advance... Kevin
