Dm performance Ls main girdles
I had a DM girdle and fitment was great you only need to trim two studs and use washers on the windage tray, now my opinion is they don't do anything worth getting them for.
A much better investment is getting the 6 bolt block with 6 bolts heads and that is your best girdle investment in my never to be humble opinion, as sealing combustion pressure is where the mayor issue is.
The lower part of the LS block is the best design area that family of engines.
