welcome to the site! AS far as I know, the floor mat should be interchangeable. On the taskforce trucks, (55.2-59) the big bolts have a park brake lever on the transmission that the smaller trucks don't have so, they have an extra hole in the mat but, that is pretty easily remedied. The rest of the cab pieces are interchangeable on the newer ones and I believe should also be on yours as well.
Nice looking truck you got there BTW!
