Hi Guys

I know this topic has been done to death a little but my question is a bit left of centre.
Ive recently picked up an SB 45 20" and im %99.9 sure there are no cracks in the rails.
I plan to refurbish it at some stage but my question is if i do decide to strip it down should i get the rails strengthened whilst its apart or am i better off
leaving it alone ?

regards
Peter G
