Rear sub-frame differences from 83 to 85/86 and a rear camber mod question..PICS!

[CarlH]

[QUOTE=ABQMK2;765338]Now I need to run this through my friend parts washer at his machine shop..paint it up nice and black, press out the bushings and install my super pro bushings...install all new rear wheel bearings, seals,crush sleeves...put on my rear BBK with cross drilled rotors and wilwood brake calipers with SS braided lines...then bolt up my diff with 3.42 gears and a true trac, slap it up in the car, bolt my shiney Simmons back on....meh...all these parts are sitting on the bench just been collecting dust waiting for me to do this.


Hi, As a paint prep, I like to use Castrol purple cleaner, It has an acid in it that is good to help etch the bare metal ( which is good practice for paint adhesion). It helps De rust metal if soaked long enough in it. That makes it good for cleaning gas tank internal rust as well.
It is not recommended for aluminum parts. But If you don't leave it on aluminum for long or diluted it will give a Satin dull finish on alloy.
You use water to rinse it off and the sun and air compressor to dry it quickly , or you can use a wood stove or torch to dry the parts and all the nooks and crannies. You need to dry it quickly as possible Plus it is oil free and you can do it at home.. Carl H

Awesome. Thanks for the play by play Jake. Bookmarked for future reference. I couldnt stop laughing after seeing the random pic. Glad I wasnt eating steak though, gross. This beef jerky is much better.

Wow..thx Carl for taking the time to write that..i will keep that in mind for all my future projects.

As far as this one fellas....i started to remove and grind the brackets off at 5pm..had it all welded on by 8:30...i had some help..but its not that hard to do..i just made sure to use the lcas as a jig and made sure the camber mod brackets were as low as possible and flush against the subrame squared and even.

Thx George for the instructions...they just confrmed i did most of it right..lol!

I recommend supraholics thread as well Rob ...his pics are excellent and so is his description.

ABQMK2,

I hope you added some gussets after your last picture? I did not see any...

P.S. That round piece with two bolts is a harmonic dampener.

Regards,

Carlos

[ABQMK2]

Thx carlos, thats as far as i got last night, had to stop for some sleep for work today. I will make gussets and finish it all up here shortly.

Question guys: for those superpro bushing.install..easiest way to get the old ones out?

Press them out?
Burn them out?
Cut them out?

Link to how to.thread?

Here and here is Wes's approach....there's more than one way to skin a cat but you asked for links and i has links for you...

[ABQMK2]

Good Ol' Wes! Love his write ups. Thx again George..i would of been using my shop press WD40 a blow torch and Eric in the peanut gallery drinking and egging me on..basically it would've looked like a monkey fuggin a football..which is normal in my shop!

No football is safe in my shop...ever!

the 86 has these bump stop things as well and my 83 doesnt

IIRC, that's actually a harmonic balancer - something having to do with vibration tuning for the rear end - Damon can explain it better than I can - we talked about them at a NE meet a few years ago.

[Funkycheeze]

That balancer, and the reinforcing gusset near the diff mount are 85/86 specific. I wish my 84 had it, as the big power and sticky tires started cracking the whole diff mount off, until I reinforced the shit ouf of it with some welded on steel bar sections.

[SupraFiend]

The balancers are 86 specific actually, not sure about the gusset, 85s may have that too. Will have to remember to check tomorrow.
