It takes a set of special front fenders to complement the relocated front wheels. Rich has handled this many ways on the seven Match Bashers he's done so far. If he wants to spend the time and has them available, he'll take a set of standard steel fenders and move the wheel openings ahead, then weld in carefully formed steel patch panels. It's time consuming, but yields mirror-smooth results.
If he wants the car to be a little more authentic (read: rough), he'll score a set of reproduction fiberglass A/FX fenders from an outfit like Fiberglass Plus. They already have the altered wheelbase, but require some finessing for good door gap and hood fit.
There's a third option that Rich hasn't selected . . . yet. It's a super-butch move where the stock wheel opening is left where it is, but the leading section that would come down and interfere with the tires is simply sliced off horizontally. This treatment yields a rude WWII army Jeep vibe, but was seen on the funny-fied '65 A990 of Texan Ted Detar back in the day, so there's a valid historical precedent that makes it OK by Rich.
The whole issue of what is and is not correct or appropriate for today's Match Bash builder is a hotly debated topic. Rich says he'll try anything as long as he can find one or more photographs of the detail in question published in a drag racing magazine dated 1967 or earlier. Trends, techniques, and parts newer than the '67 racing season are shunned. We're cool with that since it keeps the Match Bash theme untainted by modern touches that can quickly ruin the buzz.
One big exception that Match Bash builders such as Richard happily embrace is modern electronic fuel injection, as long as it is subtle and hides in plain sight. Old Hilborn IR (individual runner) injection intake manifolds are a key touch on Match Bash creations with their forest of ram tubes sticking through the hood like porcupine quills. In fact, the only other "correct" choices are Holleys on a factory-style cross-ram (to replicate early stage, NHRA-obedient, legal '65 FX cars) or a 6-71 supercharger (used later on the all-out "run-what-ya-brung" '66-'67 match-racing circuit). But the old mechanical pump, barrel-valve technology sucks on the street.
There are several companies, such as BDS and PTR Injection, that specialize in EFI conversion work, or you can even buy a new Hemi intake with integrally cast EFI bungs from Hilborn, Crower, Kinsler, and others.
