LS1 vs. LT1 rear brake info

[justforfun]

I am in the middle of putting LT1 rear disc brakes from a 93 camaro on my 67 firebird & thought i would share some measurments.

I measured the thickness of the rotors and drums to determine total rear width trying to avoid tire rubbing with 275's.



.110" 67 firebird drum thickness (think this is stock, they were on my car when i bought it)
.125" rotor thickness from 93 camaro
.250" rotor thickness from 98 camaro

By the casting numbers and c-clips my rear seems to be from a 67 camaro, & measures 59-13/16" outside axle - outside axle.
