Anyone know the filling you buy at the hardware store to fill in the rear mount making it stiffer. I know Hasport makes a stiff mount but just wondering if I can make one without spending $150 on it. Also, anyone have any idea on top of their head to wire a Five-wire HX primary O2 sensor into a GSR Four-wire? ( Like which wire is to ignore and which wire extend to the ECU?) It's a 98 Civic HX fitted with 98 Integra GSR, right now using HX ECU but need to pin the GSR one in, only Primary O2 sensor left to do.

 

Why not just get the ES inserts and only use the rear set?
$30+ shipping.

 

The Stuff you need is made by 3M, it's used for installing auto-glass, can't remember the exact name. Should be available at most auto parts stores for around $15.
