Question for the TR gurus out there - I am looking to replace the engine compartment foam that sits on the underside of the engine hatch. I can't seem to find the part of the Ricambi site. Has anyone replaced this foam and if so, did you use the original OEM stuff or has anyone done an upgrade? I'm wondering as well if Ferrari changed it on the 512TR as the OEM stuff that's on there now is crap. My car is a 1990 Testarossa. TIA.
