Nice

What about shackle to frame?

Download your cars factory service manual.
All the info and procedures are in there.
 
Download that manual. I doubt you have tapered axles in there and 145 on those nuts without the tapered axle will prob snap.

You have to watch when you tighten the rear shackle nuts... The mancini racing shackles WILL NOT TAKE THE TORQUE SPEC'ED IN THE SERVICE MANUAL...

You just snug them... If you go too tight, they will break... I recommend getting two sets, so if you break one, you will have the "feel" for when they will break and then back off just a bit...
