Well thank you it all makes sense now.

I have had a seized front caliper smoke and get red hot.

The Craigslist dude refused my offer for $100 even though i am a repeat customer. I did ask him if he wanted to give me reasonable counter offer.

I will look at a new replacement axle but i have the tendency to go for the cheapest i can find.
Is that a mistake?
I do want to find a quality bearing like a timken, the advance auto brands concern me and i think the one i put in my truck is already starting to make noise.
As far as how i will use the car is hard to answer. There is my dream plan then a more likely reality plan.

Dream is a healthy build of my 400 and a super t10 4 spd to be mostly street driven with frequent smoke shows on drag radials so i can see what it would do at the track. I would still use my 6x heads so i am guessing hp maybe 400.

I doubt i would ever be on slicks unless i came into some unexpected money.

The reality is having to use my 350 with the automatic on street tires with frequent burn outs.

I ordered my 80w90 gear oil and GM posi additive but still need to source the axle and bearings and seals.

After reading what I have written I am realizing it is stupid to buy that rear end for parts because then i have a rear-end i can't use in the other firebird It would be great to have two rolling cars.I do have two driveshafts and two sets of leaf springs and two motors.
