HP to LP reg conversion springs

[vmaxnick]

I have a couple of HP pre-set regs I want to convert to LP
Anyone done the reverse and have some LP springs knocking about I will buy them or swap and pay postage both ends.
I know I can buy them new, but they aren't cheap considering it's just a poxy spring

I have an lp spring of a totem air reg if any use.

Yes mate I presume it's a pre-set (bottle) reg?

How much would you like posted?

DISCLAIMER: I do have the facilities to strip regs and test the output pressure!
Please don't try this at home!
