Undercarriage springs

[Guest Waz]

Hi I'm new to Recreational Flying Site, I have a Thruster 85 which I first bought in 85 and re-bought this month. It has the curved undercarriage springs that keep straightening out,I've always wanted to put the straighter springs on it that look the same as the two seater's.Is there anyone out there that has the dimensions willing enough to pass them on to me.Thanks in advance, Waz
