This may be a thread somewhere in here but I can't find it. I'm building a 29 coupe and had my front end setup with Model A split bones. Don't like them as they are to small. Bought some mid 30's bones that are a lot more beefier but now my spring perch's are to short to clear the axle and get the nuts on. Do you guys mill the bones or just buy longer perch's? To me you would get longer perch's so to keep the thickness of the bones. I don't see longer ones at Pete and Jakes and such.
