91.5-93 intercooled pump/throttle bracket, bolts to block and that one 10mm bolt the injection pump at the bottom bolts to. Cummins part number 3918949.
91.5-93 IC'd throttle bracket, mounts underneath the cylinder head, then the throttle bracket itself (same between intercooled and non-intercooled trucks) bolts to this small bracket. Cummins part number 3918947.
Both of these two will make installing an intercooler in a non-intercooled truck much easier and more of a bolt up job. It can be done without though using all nonIC'd parts and with some fab work. If one was to be pulling the intercooler, injection lines and associated IC'd parts off an IC'd truck at the junkyard, it would be wise to grab these two brackets.
