I recently purchased a fact. gauge cluster out of a 1981 c-10 1/2t 2wd donor truck with plans on installing it in my '81 c-10 1/2t 2wd. My problem is I damaged the case (tach. gauge) during removal. Everything is still intact except the top mounting bracket (for the bezel?) broke and the housing also cracked. Can I use (switch) my original housing?
