Well i was able to score some 2007 mustang seats for my 65 Mustang and started to get them ready to put in i only took a couple to pics but i will take more when i do the drivers seat it got dark before i could get it out.
I started by taking the bolts off the passenger seat you have to access them from under the car there may or may not be some rubber plugs on you're car. once i got the passenger seat out i pulled the tracks off there is a large spring attached to the track and seat frame that you will have to remove, there is also a rod that connects the seat track adjustment levers together but that wont come out until the tracks do.
Once you get the tracks off the old seat its time to work on the new seat there are electronics galore under here depending on what type of seats you get i got both manual so i didn't have a lot of stuff but there was still the airbag weight sensor and the seat belt sensor.
the track assembly is held on by 4 nuts they are inside the seat frame and hard to see and get at. i had to take a 15mm box ratchet wrench to get at them and take them off after i taken them off i was left with a trackless seat.
The holes marked with a red arrow are 14 1/8 inches apart and that just how far apart the old seat track need to be! i took a 5/16 drill bit and drilled out those holes i put 3/4 spacers under the tracks and bolted them down i then measured the tracks outside to outside and got 15 3/8 i made sure that the top was the same then marked the top holes as there are not any pre drilled.
This is the top holes marked
i drilled a pilot hole first then finished with the 5/16 bit with the tracks bolted down I reinstalled the springs and the adjustment lever tension bar.
with the tracks fitted i put it in the car to see how it would look!
You will have to bend the Adjustment Lever on the primary seat track so it will not hit the front of the seat but it bends easy and dont need to heat it. also you will need to trim the plastic on the side of the new seats so they wont drag on the carpet i trimmed mine about 1/2 or so
This is the spacer i used its 5/16 ID and its nice and thick for strength i also used grade 8 Bolts washers and nylon locking nuts. when bolting the tracks down if you use hex head bolts make sure the sides of the bolt are parallel to the tracks that way the tracks will slide over them with out hitting i has this problem they dont hit much but this will solve it!
Here are the installed pic!
I have about 3 1/2" of head room with this seat and 7" of steering wheel to seat clearance with the seat like you see in the pic and its like a whole new car driving around with those because your not trying to slide around like you do with the old seats
and yes i am going to get some blue seat covers until i can get enough money to get the seat redone in blue!
