Engine Cradle on 1997 Oldsmobile Regency

I found out the popping noise I have been hearing is the engine cradles both sides front and back need replaced.Frame seems fine, 2 in front and 4 in back.The 2 the farthest back are completely gone.No bushing in them at all. Are the other 4 sufficient at this point? I hate to put a lot of money in it. The other 4 look pretty good.Any idea on what I should expect the cost to fix this problem to be?

Dealer will charge about about 1500 for the part . many other parts are probably deteriorated as a result for a whopping $3900
