Hi Sergio.
*IF* you've got a "Series" Alpine, 1959-68, I'd use these steel thicknesses:

Central sill, A post, B post, Cruciform, front & rear spring Hangers and
all 'chassis' sections
need to be 1.8 mm or 2.0 mm mild steel (British standard wire gauge s.w.g.
16 - 14 ). No thinner.

Any other 'structural' stuff i.e. sills / arches / floors / internal panels / :
 use 1.6 mm ( swg 18 )

Outer panels i.e. wings / door skins etc you could use use 1.0 mm or 1.2 mm
( swg 22 / 20 )

if you've an earlier "Mark" Alpine, I can't help you, sorry.
why not tell all of us a bit more about the cars ?
