I've missed loads of this thread, just sat and read through it all, going to be a cracking car.
Cage install brings back some memories! The front X through the bulkhead will most likely just arrive as two lengths of 25mm tube, they let you cut and profile them your self. Cutting the holes takes a bit of figuring out, or just cut them big and plate it back in lol
Your man is pretty handy at Tig!
My mate has been giving me some more welding lessons, finally starting to get a bit better at it now, even doing some important bits myself
Regards lowering and or moving the steering column, be aware, if you move it too far from stock you run the risk of effecting the operation of the column. The phasing and operating angle of the two UJ's is very important if you want to maintain smooth, linear steering.
I've moved the column on my car down quite a lot and also inwards slightly,
I initially used a single UJ but I knew it was right at the edge of it's adviseable operating angle at 22degs +/-
In order to check, the column is turned through 20deg intervals and the amount the rack moves measured with a vernier caliper, this should be linear but as i suspected it was anything but.
I ended up fitting a double UJ in the middle and a single one at the rack, the difference was quite surprising. I've not got any pictures of it but i'll update my thread soon.
Keep up the good work.
