I'm trying to finally re mount my cab it's been off for about 2 years (all done now) my mount kit has 4 rubber squares about 1.5 inch. Do all 4 go in the front. I have the 2 front mount bolts, then it appears there might be a 2nd set of bolt holes on the cab and mounting brace just inside those main mount spots. I don't remember, and the shop Manuel is really basic. Please help.
