My2nd73

1st post, so thanks in advance..... Does anyone know if there is a step machined into the flywheel in the area of the pressure plate attachment; or is it just machined true all the way accross? ( stock application) I found no reference at all in my factory sarvice manual! It's a stock 73

in my 83 theres a 1/8 groove right around the disc. but it's true all the way across. that how all of my z's have been (78-83).
