what width and tires size work well? I'm thinking of using 65 series tires if they won't rub on anything.

If you need and help on a front end build let me know. I completely redid all the suspension and brakes on my 1969. I am assuming its pretty much the same as your car as well.You're welcome. Keep us posted.
One of my main goals was to make sure my tire diameters were the same, or nearly so, front to back. Many years ago I put G60-14 tires (which is dating me, because tires aren't sized by letter codes any more) on the rear of a 1968 Mustang. The wide rear tires were visibly smaller diameter than the front tires, which looked wrong.
I may pick your brain about the front end rebuild, which I need to do.
If your car has the C6 with the 429 then I think its all the same. They didn't really change much in 1970 over 1969.Unfortunately, Classic Tube doesn't have the transmission cooling lines for the 1970 Thunderbird. They have the ones for your 1969. But thanks for the lead, I'd not heard of Classic tube before, and they have other pre-bent tubing for my car.
I got all the pre-bent tubing for the brake system. It's about 85% correct. The lines at the rear are perfect. No issues. Lines for the front two wheels I had to do a bit of "convincing" to get the brake line to the passenger side wheel along the crossmember, behind the upper control arm and then down to the flex line. The bends were a little off. The lines that go into the master cylinder look good, but getting the old lines off the brake balance distribution block was not happening for me. The just wouldn't budge. Fortunately The were not rusted. The benefit of grease and oil being thrown everywhere I suppose. So I just left them on and kept the new ones as spares if I ever need to use them. I didn't use the long line that goes to the back as the previous owner already replaced that line with a stainless steel one. the lines are annealed stainless so there is quite a lot of flex if you are careful and need to get them to bend.Unfortunately, Classic Tube doesn't have the transmission cooling lines for the 1970 Thunderbird.

I had one for my rebuild. Just search for it. I have all the pictures of the complete rebuild process of my 1969Thanks for the information, much appreciated. I will definitely give Classic tube a call.
I've given this a lot of thought, and you're right, it will be a pain. I plan to pull the radiator and grille and fish the transmission cooling lines in from the front. I need to get the radiator cleaned and rodded and have a pinhole (or three) fixed. So I'll just do all of that at once.
I'm also going to do a leakdown test, replace the water pump and fuel pump and do a few other housecleaning things while I have the radiator out.
I think we have completely hijacked this thread, and I apologize. I should start my own thread. Do people do "build threads" on this forum?
Thanks for the great info. I'll check it out when my front end rebuild is complete.

Yes on the front coil springs you will DEFIANTLY need a spring compressor. No other way to get the front coil springs in (or out) without one. Also I used a jack under the control arm to compress it enough to get the lower ball joint into the knuckle of the spindle. BE VERY CAREFUL! Those front springs have A LOT of stored energy and could hurt you REAL BAD it they pop out. Rear springs are cake. Just lower the axle enough and they simply fall right out. WARNING! remember to disconnect the rubber brake line coming from the frame and going to the axle when you lower if you do plan on reusing it. There is only so much it will go before you tear it off. Check and make sure the rubber pad is still okay for the top too. That cuts down on suspension noise, and just help protect the frame itself. Rear springs had a rubber pad on top and bottom.On your rebuild, did you need a spring compressor?
TIA

Drilling out the rivets on the upper ball joint was a PITA when I tried. I used a cut off wheel to slice off the top of the head enough to see where it went down through then drilled a hole and beat the rest out with a punch. Just cut into the old upper ball joint housing if you have to. It's not like you are going to use it anymore anyway. Lower control arms are actually still available to purchase complete with the ball joint and new bushing in it. Problem is reinserting it back into the crossmember. There is two washers on either side of the control arm (shims if you will). They are originally tack welded into the inside of the crossmember. The issue is when you try and wedge the new control arm (or old one if you manager to get the bushing out) those washers will most likely break free and fall out. Now on one side I spent a considerable time wedging it back in. The other I got smart and just sanded down the one side so it was slightly thinner and it slid right back in.
If you need to know anything else let me know.
EDIT: Oh by the way our cars don't use a double A arm system. They use an upper A arm on the top ( I believe 7/8 bolt holding it to the frame with the outer nuts being 15/16)with a single control arm and tension rod connecting to the front of the frame.
EDIT EDIT!!: Lol after watching that video there is some thing'that are different. For one thing our ball joints are not pressed in. They are originally riveted from the factory. The new ones are bolted.
