67 Firebird - Project start date 1981

Cool project! I had a '68 back in the early '90s, with a 400. It really could have used those traction bars, but then again, tires back then offered much less grip . . .

Here's to continued progress!

So I'm debating what to do about the rear axle. The stock unit is a 10-bolt, 8.2", BOP, UW-axle code meaning 3.55 & LSD. Not exactly a desirable unit. At one point, I had a Chevy 10-bolt I thought I might build for it but I ended up selling that unit. I have a 9" Ford with a Detroit Truetrac that I built for another project, but it is 1-1/4" wider and has no brakes setup on it - I don't recall the gear ratio - 3.55 or 3.70 something like that. I have an extra pair of monoleaf spring perches. I also have a set of adjustable Koni shocks (NIB) for the stock suspension.



The primary use of this car will be Autocross, HPDE and some daily driving. I have no expectations that the car will be remotely competitive - just fun to drive.

Option 1:
Rebuild the stock unit, install a new LSD, buy new springs, use the Konis and call it a day. $

Option 2:
Weld perches on the 9", buy new springs, use the Konis, have a driveshaft made, buy a brake setup, figure out the proper wheel offset and what will fit, deal with different bolt patterns front vs rear, etc. $$

I'm trying not to overspend on this project which is very easy to do - although I haven't defined what overspend means. I just know this is not a premium example of a desirable car - translation: it will never be worth what is spent on it.

Leaning towards Option 1. Thoughts?

I spend weeks researching rear suspension options: monoleaf, multileaf, composite leaf, watts links, bushing types, etc.

I finally decide I'm gonna rebuild my 10-bolt BOP with an Eaton posi, install Global West Cat5 reverse-eye leafs with 2" drop, a Fays watts link, Koni adjustable shocks and figure out an adjustable swaybar (my current VSE bar is not).

I call GW - their spring supplier is gone, they have nothing left in stock for the 1st gen f-body and have no idea if or when they might get a new supplier.

Grrrrrr!
