Damm can't find my picture
Graham not on road so can't say if this will help.I've built a 'u' shapped structure that is bolted to the bottom front diff/wishbone tube going up to support front diff support, then it goes forward along the tunnel to take the seat belt fixing, It's bolted to the main tunnel bottom over the hole cut out in the floor and the rivets in the sides were replaced with 6mm nuts & bolts. Hopefully the sides are tall anouth to stop the propshaft leaving the confines of the tunnel if it gives way. all from 5MM steel not saving weight but saving worry
