Who has different year, make, model rear installed into their X frame?

My 78 Trans Am still has stock 28 spline 10 bolt axles and an Eaton posi 1.5s 60 fts 10.90s @ 124. Although 30 spline are in the future and what I put in the 81 Trans Am when the factory posi was worn out for it's future 455. There is a guy repoping the factory posi friction plates now.

Yep, Don's correct, Ford 9" under the 60. Narrowed and all the fixtures scavenged from a 60 Chevy donor car rear. Mosier axles and a Detroit locker, 4:56 gear. I have the upper added control arm. All arms are stock units, boxed with poly bushings. I have upper control brackets modified to raise the height for instant center adjustment.

Do you have any photos of your upper control arm brackets by chance?

Johns Industries Ford 9" positrac on my 61 Impala. Bolted right in ... had to shorten the tail shaft a few inches. RideTech suspension. The "muscle bar" wouldn't fit so I discarded THAT. It was for the OEM rear axle. Oh well. Will see what she does here in another month/so. Polly is currently at the interior shop.

If you plan on going to the track with this you best reinforce your upper and lower control arms supports!!

Nope. But thanks.

RideTech only to minimize the rolling whale I recall she had when I was a teenager. It's not a "perfect" solution ... but it's what I am taking.

Yes, these cars were not made to corner, LOL. I remember the video of the 61 409 Impala in England and watching in careen through the corners.
