For average owner, wouldn't it be simpler and easier just to change Inconel bolts periodically? For anyone who can't wait for Toby Peterson's next production run, Walt Coe (US distribution) and Martin Gutkowski (European distribution) had similar bolts -- yes, I know there are length and thread differences -- made from Inconel too: http://www.delorean.co.uk/DMUK/newparts1.html#tabs If I'm not mistaken, this is the same material that bolts holding jet engines to wings are made from.
