There really was a business by the name of Juan Fish Garage. It was located at 3036 West 7th Street, Los Angeles, CA 90005
This description was found in a collactable automobiles article in the New York Times:
Purchased from Juan Fish Garage in 1990, this truck could well be the best known working truck on the streets of Los Angeles.... Quite a claim to be sure, but for years we were regaled with stories of "Juan Fish (the man, not the truck) stole my girlfriend," I bought batteries from that guy," "Juan Fish was a lodge brother of mine," "Hey, I knew yer father" ad infinitum.... On its 2nd engine in our ownership, Juan Fish still prowls the mean streets of Los Angeles daily to the banshee wails of "Hey, do you fix fish?!!!"
How about this for a splendid vintage Chevy truck with original patina?
Here is the history of this 1st gen Chevy truck: The 1960 model year introduced a new body style of light pick-up truck that featured many firsts. Most important of these were a drop-center ladder frame, allowing the cab to sit lower, and independent front suspension, giving an almost car-like ride in a truck.
Also new for 1960 was a new designation system for trucks made by GM. Gone was the 3100, 3200, and 3600 designations for short 1/2, long 1/2 and 3/4-ton models. Instead, a new scheme would assign a 10, 20, or 30 for 1/2, 3/4, and 1-ton models.
Since 1957, trucks were available from the factory as 4-wheel drive, and the new class scheme would make this known. A C, a Conventional, in front of the series number would indicate 2-wheel rear drive while a K would denote 4-wheel drive. Actual badging on trucks still carried the series name system from the previous generation.
The cab roof used double walled steel construction unlike the other automakers who used a single steel roof. The 10, 20, 30, and 40 series, C or K, were badged as "Apache", etc. 50, and 60 series trucks were badged as "Viking", and the largest 70, 80, and 90 series models were marked "Spartan" etc.
In 1960, C/K trucks were available in smooth "Fleetside" or fendered "Stepside" versions. GMC called these "Wideside" and "Fenderside." Half-ton models were the C10 and K10 long-bed and short-bed trucks, and The 3/4-ton C20 and K20, as well as the one-ton C30, were also available.
GMC did not use the "C" nomenclature, though their 4x4 versions had the "K" designation. GMC Model numbers for 1/2, 3/4, 1, and 1.5 ton were 1000, 1500, 2500, and 3000. The 1960,1961, & 1962 model used torsion bar front suspension, with trailing arm suspension rear. Trim lines were base and "Custom."
Engines included the base GMC 305 in3 V6 for the GMC version, 135 hp., 236 inch, and 150 hp. ,261 inch straight-6's, and a 283 inch, V8 with 185 hp. A coil-spring front suspension came in 1963; along with a new base engine, a 140 hp. ,230 inch, and an optional 165 hp. ,292 inch.
The cab was changed for 1964, with elimination of the "wraparound" windshield and a new front grille design, along with various interior changes. Air conditioning and a 220 hp. ,327 inch, V8 came in 1965. A new base engine finished the model in 1966 with a 155 hp. 250 inch. Basically, the 1960 and 1961 models were virtually identical.
