Suburban floor supports same as truck??

[pete29]

Im trying to order some new panels for my suburban project. I need all new cab floor supports, along with rockers, inner rockers and probably do front half of floor on each side. Does any one know where to buy the rear cab floor supports for the burbs? or are they the same as truck? The support itself looks wider.

Have to use truck ones and modify. It's what I had to do on my crew cab.
