I waited to trim these guys until I got the seat ribs in place. The seat rips determine the amount that needs to be trimmed. I saw a log where a dude didn’t want to use his bad saw on these metal parts. Worried about dulling his blade. Well, not me, it’s a tool and the best choice. Use it. Cut fast and straight. Scotch Bright wheel and they looked great. I used the touch up paint from VANS’s and after it dried they looked like they were never modified. Cool.
