When it comes to modifying collector cars, the Buick Grand National is typically off-limits. Most are enshrouded in an air bubble in a collector’s garage, waiting for the day it rolls across the auction block. Not this Grand National, however, which sports a truck-load of custom fabrication work to marry an El Camino rear end to a Grand National front clip. Find it here on eBay where bidding is over $8K but the reserve remains unmet.

Well, let’s see if what the seller has described is actually what’s occurred here. He says, “Everything from the doors back is from an El Camino.” The only sticking point there is the window glass, which certainly is not from a Grand National, as the curvature of the roof and the top of the glass doesn’t match the upright roofline of the GN. However, it is identical to El Camino glass, so does the seller mean to say that he simply swapped a GN front clip onto an El Camino?

In no way is this a rip on the work undertaken to build this custom creation. But it would be helpful to know if the rear end of a Grand National was sawed off and an El Camino rear quarter grafted on (which is quite invasive) versus simply swapping the fenders, lights, grille and hood from a GN onto an existing El Camino. The latter would possibly indicate less potential for rust or other body issues down the line. The interior is 100% Grand National and quite tidy.

The engine has been freshened up with a top-end reseal, new plugs and wires, a new alternator, a custom exhaust and new A/C compressor, among other upgrades (I wold take it to mean the A/C isn’t in need of a charge). There’s a a laundry list of maintenance, performance and custom upgrades in the listing, but an in-person viewing might still be necessary to assess the health of the bodywork and other elements of the conversion.
