I have a 66 with a 390, 3 speed automatic. I'm looking to put in a tko 5 speed and was curious if anyone has done this. I'm putting together a parts list but want to make sure I'm not forgetting anything. Any help would be greatly appreciated.

I put a T5 in my 62 and it was not a great fit. The TKO is quite a bit bigger and will require some surgery to the flor pans to get it to fit. What parts are you planning to use for:
bellhousing
clutch
transmission crossmember

Great, not the news I was looking for...
TKO 600 26 Spline long input shaft
Quicktime FE Bellhousing
Hydraulic clutch, but i have the z bar and clutch pedal assembly from a 66
I'm still trying to figure out the crossmember as i've never done this before and making sure I have everything before I get started. Hope this info helps and I really appreciate you getting back to me.

Can you weld? if not this will be a daunting task. you will need to build a custom transmission crossmember. There are two min ways to do it, first you can build a crossmember from scratch (thats what I did) or you can take the stock cross member and cut it into thirds. You then position the transmission where you want it, bolt up the three pieces where they go, and weld in some steel pieces to bridge the gaps.
As to clutch actuation there is the hydraulic throw out bearing or an external slave cylinder. I prefer the external slave because you can still feel what the clutch is doing through the clutch pedal just like you can with mechanical linkage. I sell a kit to put a hydraulic clutch in a TKO, let me know if need more info on it. (not trying to make a sale just letting you know its available) if you want to design your own setup and fabricate it your self I would be more than happy to help. Let me know what questions you may have and what else I can do to help.

Actually, not at all! But, a buddy of mine that will be helping me can. I was hoping I wouldn't have to cut up to much but I guess its what I got to do.
I was still investigating the mechanical vs. hydraulic clutch. From what most people said, I gathered it a lot easier using the hydraulic. The parts I'm looking at would be a Wilwood master cylinder along with a Super HD FTE concentric slave cylinder. But, I would be interested in getting information on the kit that you sell as well. It doesn't hurt to look at all avenues. Especially for me who doesn't really know yet what I'm doing.
Thanks again for all the help

First let me make it clear that I am happy to help you no mater what. If you get the parts from someone else and need help getting the pedal ratios and such figured out and/or figuring out MC and SC size I can assist there too.
This is what I offer, if you follow the link there is lots of information on the kit
Let me know if I can be of further assistance.

Thank you so much for all the help and I'm sure I'll need something. I will definitely look at the parts you have available. Did you switch out the Differential as well? I almost want to do everything at the same time, but it always boils down to how much money I want to spend

Do you by any chance have any pictures of the work you did to the cross member? Or the transmission tunnel? I want to show my friend who does welding and body work to see if he can help me with the project. Thanks again for all the help.

I recently installed a 4R70W transmission into a 61 Galaxie. I simply cut out a section of the original transmission crossmember, installed some heavy flatbar and reinforced with gusset plates. Doing it this way, I was able to keep the correct locations for mounting the emergency brake cable. Not sure about your transmission mount and location but this method may give you a starting point.

In my car I put a T5 rather than a TKO/3550 so I did not have to cut the floor boards however it was extremely tight fit and I probably would have had a better fit if I had cut the floor boards a little In your case the TKO is quite a bit bigger so cutting will be required.
Here is the concept behind the basic technique for modifying your OEM crosmember. You make two cuts, install the transmission and the pieces in the car, then bridge the gaps with some steel pieces and weld them in place.
I chose to make a crossmemeber from scratch using 3/4" square tubing and the e-brake bracket from an extra crossmember I had.
Next two pictures are my bracket compared to the OEM bracket. not only were the mounting holes in a different location front to back but the bracket had to be deeper as the T5 is a lot taller than older transmissions.
