1971 Ford T-bird parts & problems - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Hey there, I'm new to the forum here, and I just bought an old 1971 T-bird yesterday for 800 bucks. It's going to be a restoration project of mine. It drives fine, and sounds mean!

However, if I go hard on the pedal, I notice the transmission has a bit of a tough time getting into 2nd. This only happens sometimes.. I noticed that after driving around town for about 20-30min, the transmission shifts a lot smoother. Why is this? I've only got highschool mechanics training, so forgive me, my knowledge is quite limited.

Also, the rear springs are shot, so I am in need of some replacements. Can anybody forward me some good websites to order parts from?

Hi J.Pahl. Welcome to the forums.

Try RockAuto Auto Parts. They have the springs you need for around 90 bucks for the pair. They also have a 5% discount code for all fordforums members RockAuto Discount Code - Valid through 10/27/2011

As for the transmission, have you checked the fluid level?

Yes, turns out the fluid was low, after all the car had been sitting for quite some time. Shifts fine now. Going to get rear coils and springs, order new exhaust manifolds, and order a couple of straight pipes. Any recommendation on size for the pipes? I was thinking 2.5".
The fun begins!!!!!

What engine ? What H.P. ? If under 300 H.P. with duals 2.5 is too big. You don't just slap
pipes on an engine and hope it works. Do some research. Put 3 inch pipes on what ever engine you have and it will slow down.

Chip is right about pipe sizing. 2.5" will be fine with that engine.

Cool, thanks! I've been eyeing up some flowmaster 2.5" pipes.
I've been having a lot of trouble finding headers though..it'd be nice to get performance headers to compliment the performance exhaust. There seems to be plenty of headers for all models up to about 66'. Any recommendations?

Headers for a 71 T-Bird would be almost impossible to find. I guess you could try finding shorty headers or a weld up header kit. I wonder if headers from a 71 Torino would fit?

Might try contacting these guys http://www.sandersonheaders.com/
