now most guys never bother, because its seldom a problem on the street driven cars or while drag racing, but if you road race where theres a constant load on the rear differential and MANUAL TRANSMISSION its going to be an excellent idea to have a manual transmission and rear differential fluid cooler installed.
large finned differential covers help disipate heat but they are not always efficient enought to remove and transfer heat fast enought to prevent the lubricants from degrading due to excess heat.
most manual transmissions and all differentials Ive seen will require a small pump to be installed too move the fluid thru the cooler, I mounted my oil cooler where the rear tire is normally stored for easy access.
IVE seen BOTH dry sump oil pumps and salvage yard supplied power steering pumps adapted in the past to move rear differential and manual trans fluid thru coolers so having a bit of thought go into the process of designing the system helps
most manual transmissions have an upper fill plug that can be used to mount the return line and lower drain plug that can feed the fluid pump, most rear differentials will require some custom plumbing to allow a cooler to work, correctly, but doing that by tig welding 3/8" NPT bungs on the upper and lower back surfaces of the differential cover allows you easy access without machining on structual components that might weaken them
