Wanted: new/good twin shocks for 1980 PE175 Suzi

[Beeza]

I'm 120kg and I bottom out the soggy twinshock rear suspension of my VMX 1980 racing PE175 --- running original 27 year old shocks. Need ones with far stiffer springs and decent damping. Do any of you know what's quite good out there and also decent value for money --- new or secondhand? Nothing state of the art, but just pretty good kit? Perhaps some of you can give me some advice?
