Cab mount bolt length?

Doing cab mounts on my 11 dclb. Had to cut both of the rear mounts with a sawzall, due to bolts seized in the sleeve. Haven’t got the bolt top free yet, but want to find new bolts. Does anyone know if the bolts are the same length for the mid and rear mounts? Mids came out easy. The mid has a thick 1” ring on top of sheet metal but can’t tell if the rears also have that yet. Looking for length as going to hardware store, not the dealer.

 

i need some bolts too, tagging along

 

What a horrible job! Had to cut both rear mounts due to bolts siezed/welded to sleeves and took FOREVER to remove the M10 bolts due to heavy rust. The bolts are m14 and a minimum of 120mm length. Couldn’t find anything local that was longer than 100, so used grade 5 7/16x5” bolts. Only about .025” thinner than the m14’s. Will have to be good enough.
