Hi there,
Nice motor, you really should upgrade to a worldcup Xmember, you have 3 options
Group4 WCXmember - Probably a bit much, it is reinforced and not really required even for a "hot" pinto road car!
WCXmember (Standard) I have one of these on my escort - they are good and have been around since the seventies!
WCXmember (For Heightened Cars) For cars that have been heightened at the front, Stops the bumpsteer. Xmember has slightly different geometery
Remember that if you go for a WCXmember you will also need the enginemounts to go with it, these come with a Sandard bushing
