Dwight a couple of long street ride boards will probably fit the wheel base of your Porsche. Not a bad idea with or without the nails.
Hi Paul. Well, after owning the 550 Spyder for some 14 years, I finally sold it off and to my air-cooled/flat-4 mechanic about a year and a half ago, and in its place purchased a slightly used 2020 FIAT 124 Abarth Spider like this one here...
True though, not that much bigger than the old 550, but it's sure nice having the modern conveniences of A/C, ABS, cruise control and a Bose audio system in it, and as compared to the bare-bones 550.
(...ya know, one starts appreciating those kinds of features when they get to be an old fart like I am now days) ;-)
