Hi, I am wanting to put a bolt-in parallel 4 bar in my MGB-GT.
Option 1
It has 6 really good strong mounting points factory fitted with crush tubes, so can I build a bolt-in frame that will support the 4 parallel 4 bar and coil over plus fuel cell.
The bolt holes in chassis are two each side at the back where bumper bar mounted then two about 1500mm away and two down the bottom that where front spring mounts.
Do I need to use 75x50x3 RHS or can I use something smaller as the MGB chassis is still there and these are a very strong unit?
Option 2
Can I use 3mm plate laser cut the same shape as side of chassis rail with 25 mm holes about 200mm apart so I can weld to existing MGB chassis plus weld around the outside edge and just butt weld the rhs rail to this?
All weld will be tig welded; I think this would be lighter.
I do have the lvvta bible but cannot find out much about welding fish plates to panel steel which is 1.6 or 1.8 thick;I think 3mm plate should be fine.
Thanks Mark
