got some time on the car tonight, managed to finnish removing the raer of the tunnel and the old diff mounts. then got the main framework in for the new tunnel

old one was pretty naff imo, was just sheet steel ontop at the front so the tunnel wasn't tied in properly which must have meant the torsional rigidity was nowhere near what it should be for this type of spaceframe.
anyway, now sorted

used 1" box with a 1.5mm wall to strengthen things up a bit, also tied the new tunnel into the bulkhead properly and secured it to the second front bulkhead bar as well as the first one. will start putting some of the other braces in after the weekend as im kinda tied up till monday. but she's starting to look a little better now
