ive got a 4age 20v(silvertop auto) crank and block
and a e58(ae101 gtz lsd) flywheel.
then i found these spacers.
im 99.9% sure one is from my old 4agze setup and the other is form the auto 20v.
so im asking for confirmation on which one to use and where exactly it goes
e.g
between crank and flywheel or between flywheel and bolts.
note
one is around 3-4mm thick (left)
one is dished and around 1-2mm thick (right)
