The condenser, compressor, receiver drier, compressor mount, AC belt, belt tensioner, evaporator, discharge line, suction line, dash switch, evaporator line. You will need a body plugs for the holes in the firewall from the evaporator lines and discharge hose, and the duct from the blower to the dash vents to replace the evaporator. You can leave the AC harness and condenser fan in for extra cooling. Another option is to have your AC system converted to R134a type of refrigerant, if you want to keep it.

To really convert to r134a you would need a bigger condensor. Just running adapter kit it will function but not to its full performance. Theres something called hotshot that has almost same characteristic s as r12. (boiling point).

No you do not need to replace the condensor, you need to flush it along with everything else, to remove all the mineral oil, you need to replace the filter/dryer, use Ester oil as the lubricant, charge to 80%-90% of the R12 charge with R134a refrigerant.

Although this will not get you temps. like the R12 system, [no R134a will] but vent temperatures of below 10 degrees C are easily attainable, take my word for it, my shop... http://www.airwolfeautoair.com/index.html.

To OP, what MikeM said, here are the parts...

Leave the rad timer, #3 or do a little rewiring.

Replace the A/C unit with the duct, #9... http://www.acuraautomotiveparts.org/...ystemcomp=List All&vinnoT=&trim=&trans=&view=normal

Retrofitting an A/C system, [converting from R12 to R134a] is not that hard to do and relatively inexpensive if you do most of the work yourself, leave recharging to a shop.

With that said, keep in mind you have a 21 year old car, meaning 21 year old A/C components that may or may not still by working properly. 94

Your 93 Suburban will also be an R12 system, that will need a retrofit to R134a, the process is exactly the same, except your GMC uses an "orifice tube" instead of an "expansion valve" and it will need to be replaced, if you have a duel system, [read A/C] the rear evaporator still uses the expansion valve, no need to change it.

It also uses an accumulator instead of a filter/dryer. 94
