To cut or not to cut. I have a 67 coupe 6 cyl. 200 that i am changing the oil pan gasket in. I have only had the car for a couple of mths. After removing the sway bar and all pan screws, the pan gets wedged between the crankshaft pulley and a "cross member" that has been welded on. I have been told that this cross member was originally bolted on only. Should I and can I without harming anything, cut the weld off and then retap the original holes for any future need.Was this cross member an original piece or is this something that was but on over the years. Will I disturb or damage anything if I do this?
