i did a google search and didnt find any install instructions / videos , but a new compressor is the next project and i dont know if teh rear is leaking , but i dont need it anyway so i might as well delete it instead of finding a leak afterwards.

@Mooseman i seen you nade a comment about doing this , but the orfice tube should be different ? should i be getting a a/c kit for a short wheel base ? im having a local ac shop do the work , just want to have all the right parts

Because you're converting it to a front only system, capacity and pressures will be different so you should replace the orifice tube with the proper white one. In any case, it should be replaced whenever the system is serviced. You still have to use the receiver/dryer for an EXT though. Use the lower oil and refrigerant capacities for a single system.

Compressors are the same. Block offs are straightforward.

just use a SWB AC hose. and if you are taking it to a shop, they should be able to figure that out. I know because I have sold a mechanic (good friend) a SWB hose that he ditched the rear AC on a LWB with rear AC.

That's also another option.
