I was asked about what was need so I wanted to make a parts list and info about this for others.
First off I want to make it simple for people that just want to spend the money and not do a ton of extra research.
This is the company I am buying the Transmission from do a google search not one bad review you can call they will answer and help all day great customer service. (((You can call them and they will sell you everything needed if you don't feel like shopping around)))
Also no shipping on most items or taxes in the long run its worth just buying everything from him.
The 5&6 Speed Specialist | Hanlon Motorsports
Now for the guy like me that wants to shop around (Want really save unless a big sale is going on) and fully understand what he is doing.
This has a ton of good info on it too get you started.
Bellhousing this is the biggest problem stock T-5 is a 9 O'clock but everything I could find says you are going with a 7 O'clock bellhousing. Why does this matter many have problem with the long tube headers and the clutch fork.
Bought from Hanlon they are cheaper than others
QuickTime Bellhousings RM-8031 (the pivot ball didn't work with my dual friction clutch I ordered Lakewood #15502)
Clutch Fork (This will fix the problem)
M-7515-A 94-04 Mustang Clutch Fork 5-6-Speed
Flywheel (One I'm using)
62631 - McLeod Aluminum Flywheel - 6 Bolt 28oz & 50oz (86-95 5.0L)
Now let talk Clutch you really have two different was to go about this. (26 spline)
First Hydraulic TOB (This way you could use a regular clutch or a Dual being the hyd TOB will make both a soft clutch)
Second (The way I went) Dual Friction Clutch
62607 - McLeod RXT Twin Disc 1000HP Clutch - Upgraded 26 Spline
I also add these
47020 - Maximum Motorsports Aluminum Clutch Quadrant
47021 - Maximum Motorsports High Performance Clutch Cable
401291 - McLeod Pressure Plate Bolts
Plan on adding (402897 - Prosport Spark Plug Wire Boot - Black) (Going to slide this on the cable to help keep the heat off it and the speedo cable)
Drive shaft (many options) read info at the top of page/link (Hanlon sales one nicer but about $100extra)
I went with this one I called they said it is rated for 900hp but I think its more if there numbers are right.
(With a .125" wall thickness this driveshaft is rated up to 5,000 pound-ft. in torsional yield and 13,900 RPM for critical speed.)
1992 Ford F150 5.0 Speedometer Cable 92inch
Part#'s Y869 $10.96 Rock Auto
03236 $12.71 Rock Auto
CA3054 MAY work also
This part did work for me (CA-3011) (Different Transmission end)
($22 after sipping and tax) at Rockauto.com (This is a good deal)
Pioneer CA3011 (CA-3011)
Lock out and wiring
Add 12v from brake light.
Nicer option 2
Halon has one also. (I bought it) little easier and nicer. Comes with above pig tails.
T56 ORDER FORM
Some pull the spring out or put a weaker one in but could be put in reverse on accident. Spend the $100
Bolts needed (Bellhousing to Transmission)
I bought this from Halon
Drive shaft loop (I'm not adding one)
Stiffler make a cool one but will raise your transmission you can fix this with a 4.1104G transmission mount.
More info to know
T56 magnum comes in 2 options
2.97 1st or 2.66 1st all come with a .63 6th before 2019 you could buy a .50 6th.
All come with electric or manual speedo option.
Gear Ratio Calculator
Its a 7 gear setup
From what I can find all shorties work.
Long Tube is all over the place (I have no idea) One person will say Mac works the next says it want.
My personal setup is custom K-member dropped 3/4in so I want be any help.
If anyone can help with Exhaust please add what you know will work but add (what k-member and motor and transmission mounts being it seems to matter)
