I'm about to do the 60k service and I see that 3sx sells a non Oem kit for $400ish USD. 60K Timing Service Kit - NON-OEM - 3000GT Stealth DOHC and comes with a Mitsuboshi TB but this kit looks exactly like the non Oem kit I can buy elsewhere for around $200 CAD... Timing Belt Kit Water Pump Fit Dodge Stealth Mitsubishi Diamante 3000GT 6G72 | eBay Both come with Mitsuboshi TB, and all non Oem parts so what really is the difference other then 3SX adding the tensioner tool and it being a 2x the cost. Going on a 1991 stealth Rt non TT if it matters. Any insight would be great.
