Update on where are have got to now.
received all the laser cutting back, this is most of it as i have used the diff parts.
Stainless exhaust flanges came out nice, not sure what pattern i will use yet, but both types match up perfect with the head/gaskets
I had marked the front brace position with the diff in, then welded in the front brace with some addition over gussets for added strength and to minimize any tendency to 'twist'.
here on in it got fiddley, i had to position the diff back in, on all the new brackets i had lasered, level the car, level the diff and then centralise. took a while with a few laser guides and inclinometers but got there. I have only tacked the front supports in and one seam weld on the rear hanger. i have also tacked 2 trianglulation pieces in, and will also fit two vertical drops to the rear to stop that twisting in the chassis.
i am a bit paranoid about the twisting as i watched a kit car programme the other day where the chassis twisted at the rear due to a non standard engine and diff being used (not this kit). so i am over egging things a little, but it should be capable of taking alot of punishment now
i will remove the diff tonite and carry on welding it all in so its all at full strength.
