Pretty much similar slope to the look of a HQ/WB crossmember or LH/LX/UC Torana crossmember.
Front mount rack also requires a small recess cut into part of the right front leading edge to allow clearance for the rack column shaft to fit and not rub on the crossmember.
A picture tells a thousand words.I've got a HR V8 CRS front end here to go in my 307 EK so will take some pics over the weekend of it and post them up if that helps but won't be able to do it until Sunday though.
Don't know why the rare spares outlet you spoke to yogie was being so pedantic about the HR crossmember being dented underneath



If they absolutely adherred to the "no dent" policy they would never get a HR crossmember as a changeover!!
