Theres an 8.8 thread on here, use the search function to find it. It tells you all you need to know.. i have my 8.75 now for the 67, so the moneys spent, however i am looking for a xploder sport trak 8.8 for the 69 notchback. I did find the only one at my local 10 acre yard, when i looked it was still under the truck price complete was $300 cash. Not bad i think , but in yellow grease pencil it said 4.10 ratio on both rear fenders. Unless you have a good deep overdrive, the 4.10s are awful on the street. I have 3.73s going in my cuda. With the tore diameter i am going to use , and an A833 O/D 4 speed box i will be about 2,500 rpm at 75 mph. Thats doable to keep up with traffic, and keep the rpms comfortable for the engine.

I want 3.73s in the 69 because i will be backing that with probably a mopar A518 out of an early 90s truck Its basically an A727 with a TCCS torque converter control solenoid. This can be wired to ign hot and a toggle switch. It basically puts the torque converter in full lockup and drops 200 RPM when energised. Around town you leave it shut off and the trans acts like a normal 3 speed A727. On the highway at about 55mph engage the TCCS with your switch, and theres your overdrive. This way it will get ok mileage and be snappy with the gears, and on the highway, its got an overdrive. Plus the A518 is a variant of the A727, so it fits an A body trans tunnel if only tightly. .

You will need the A body disc brake hoses from 74 to 76, disc brake proportioning valve for A body from 74 to 76, and the manual brake A body disc brake master cylinder from 74 to 76, and ten 1/2" RH lug nuts since the pic shows there arent any.

Also i mentioned the upper and lower ball joints and upper control arm bushings only because if your that far in you might as well replace them while your at it. Avoid at all costs the evilbay complete front end kits for $80. You get what you pay for with those. I hear moog is no good anymore too since they are made in china too. Theres 2 online places that package and sell complete front end kits with high quality parts. PST (performance suspension technology) and just suspensions.

Since your putting 74 disc brakes on a 72, you will need to talk with them directly to get all the correct parts in your kit. For example

You decide to use your small joint upper arms with the adaptor sleeves, and put the 74 up disc brakes on, you will need the 1972 kit, with 1974 disc brake lower ball joints.

If you decide to use the large joint upper arms with the 74 up disc brakes on your 72, you will need the 1972 kit with 1974 large flat rate box upper ball joints and 1974 disc brake lower ball joints.
