Thread: New rear main seal smaller?

So i have my motor out, transmission off, doing a clutch/flywheel install, and decided to change out some gaskets. I ordered a new rear main seal and its the same roundness, but the one i took out of the block was a lil bit thicker
im pretty sure all rear main seals are the same for all sr20's
is this right though? someone please help me again lol
do i put this one flush or push it all the way back so its touching the crank?

for future reference incase someone searches for this its ok, just line it up and you'll be fine

yeah the old one probably just swelled up

Haha jesse.. You and I are doing the same thing today. lol..... Mines a bit more destructive
