What are your engine mods that you keep breaking transmissions?
The 79 came with an SROD top loader 4 speed if I am correct.
That means you need a 86 - 93 bellhousing to use a T5, and maybe some different clutch linkage.
The T5 isn't much better unless you spend $$$ to get an aftermarket version. A used Tremec 3550 or TKO is a better choice if your wallet can take the hit.
A Tremec 3550/TKO/TKO 500/TKO 600 is a completely different transmission from a T5. Strong and almost bulletproof unless you run them without proper lubricant or full throttle shift without the clutch.
A Tremec T5 is still the same T5 that is prone to self destruction when used in a street/strip or racing environment
T5, all versions used in 5.0 Mustangs
Tremec 3550/TKO /TKO500/TKO600 AFTERMARKET replacement for T5 - handles racing environments with ease
See http://www.ttcautomotive.com/ for more information - check out the "Light Duty" group, since TTC makes monster transmissions for big trucks as well as passenger cars.
T5 identifier information.
On the tail shaft of the transmission, there will be a stamped aluminum tag. The tag will have a number on it that you can cross reference to the chart below. There is no other way to find out what type of T5 it is without disassembling it. All the rest of the numbers on the outside of the T5 case are part numbers which are not unique to any particular T5 model.
Remember that 94 - 97 T5's have a longer input shaft (about 11/16” longer) and can only be used with a 94-95 bell housing unless you modify or replace the input shaft.
T5's used with a 4 cylinder have a 3.93 first gear, reduced torque ratings and an input shaft pilot diameter that is smaller that the T5 used for V6 & V8 engines. The pilot diameter is .59" compared to the .668" used on V6 & V8 T5's. It requires a different pilot bearing to be used with a V6 or V8. The pilot bearing you need is for a Ford Ranger diesel from AutoZone part #14672
I don't know how you feel about the DYI thing when it comes to gears, some people don't like the idea of working on transmissions. If the DYI transmission fix idea isn't something that you would rather leave to someone else, here are some resources:
See http://www.ttcautomotive.com/English/onlineorder/product.asp to download a FREE service manual for T5 or Tremec 3550/TKO
You will need the Adobe Acrobat viewer which is also a free download – http://get.adobe.com/reader/
