Zimmer Golden Spirit Parts
Under the fibreglass an original two-door Zimmer is a Ford Mustang and a QuickSilver a Pontiac Fiero, and their mechanical parts are bought as for those cars. The hard ones are what Zimmer made or borrowed: the body, the bright work and the fittings, some of them used on no other car.

Ask what a Zimmer is made of and the answer comes in three parts. First comes the donor: a new Ford Mustang of the 1980s under each original two-door Golden Spirit, and a Pontiac Fiero under each QuickSilver, with their engines, gearboxes (transmissions), suspension and brakes. Then comes Zimmer's own work, the fibreglass panels and the trim built round the donor's cabin. Last come the lamps, horns and fittings it bought in from other makers and suppliers, the parts that gave the revival company's depot most trouble. UPI found the same mix in 1982, down to seats from Germany and a steering wheel from Italy.source 1source 2source 3
How Zimmer parts work
On a two-door Golden Spirit the doors, roof and windscreen (windshield) stay the Mustang's, and the body round them is Zimmer's: hand-laid fibreglass from the company's own moulds, with stainless bumpers and side exhausts, teak inserts in the running boards and a great deal of chrome. The rest is borrowed, and not always the same from car to car. The volunteers who ran the revival company's parts depot warned in 2000 that one original car might need different parts from another, and one of them spent more than 20 hours tracing a single fuel cap back to whoever had patented it.
Also, many of the parts put on older ZIMMER®s were "aftermarket" parts and were never used in production of other vehicles.

Golden Spirit parts
Much of what a two-door Golden Spirit carried beyond its Mustang came from named makers. Automotive News found Recaro leather seats in 1982 and put the gold-plated eagle alone at $376, and Zimmer's own sheet of May 1984 lists a hand-finished Nardi steering wheel, Mouton (sheepskin) carpet, wire wheels and stainless side exhausts. Some of the lamps came from much humbler cars: by The Autopian's account, Liberace's car wears the front indicators of a Volkswagen Beetle, and the picture in this section shows amber lamps much like them, in chrome housings, on another Golden Spirit.source 5source 7source 4source 1source 8source 9

QuickSilver parts
Under a QuickSilver the Fiero's engine, gearbox, brakes and most of its suspension stay as they were. Its steering does not: Car and Driver reported in 1987 that Zimmer added power assistance with a rack from a Merkur, which Road & Track's Jack Baruth thought in 2016 was probably a Ford Sierra's, and Zimmer fitted a very stiff rear anti-roll bar and lengthened the steering column and the radiator pipes to suit the longer frame. Its body is Zimmer's fibreglass, except the glass. Where its heavy bumpers came from is disputed: Taiwan, with the chroming done in Florida, by Car and Driver's account, or Korea, by Road & Track's in 2016. The revival company's depot had no QuickSilver parts to offer. "We don't have any quicksilver parts but do have a list of about 30 Quicksilver owners and copies of some old original Quicksilver literature," its website told owners from 2002.source 3source 10source 6

Mechanical parts
Mechanically a two-door Golden Spirit stays the Fox-body Mustang it was made from, apart from the steering and brake parts and the tyres that Zimmer changed for the longer, heavier car, so its engine, gearbox and suspension parts are Ford's; the buyers guide and the specifications give the Mustang's changes by year. No source read names the donor of the original four-doors, the Golden Spirit Sedan. The revival's cars kept their donors' running gear untouched, the later Mustang's or the Lincoln Town Car's, and the company told owners that any Ford or Lincoln-Mercury dealer could service them.source 2source 4source 6source 11
What was lost
The original company's moulds and stock did not survive, by the revival company's account: it wrote in about 2000 that the factory's contents had been taken to the dump after the bankruptcy, and that it had made new moulds of its own. No court record read confirms it. For the revival's own cars, no source read says where body or trim parts can be had since its website fell silent in 2016.source 6source 12
The revival's parts depot
The revival company opened a parts depot for the original cars on 1 September 1998, in the Roanoke area of Virginia and staffed by volunteers; its website said in 2000 that the parts list was added to and reissued every few months. It never claimed to have everything.
It is a long and slow process that so far has resulted in being able to supply about 60% of the parts used to make the original Mustang into a ZIMMER® Golden Spirit.
By 2011 the company's website put the depot's stock at more than 75 per cent of the parts, and called it one volunteer's service, not part of the company. It never had parts for Zimmer vans, coaches or motor homes, nor for the QuickSilver. When the company was sold in 2012, a relative of Art Zimmer who had joined it kept the parts business, Hagerty reported, and in 2013 the website under Heyman Motors sent owners of cars built before 2011 to the club for parts and service. Whether the depot still trades, no source read says.source 6source 13source 12
Clubs
Art Zimmer founded the Zimmer Motor Car Club for owners of the 1980s cars in 1996; membership was free, and his company said it had more than 700 members by 2002. The Golden Spirit Club had several hundred members and an e-mail newsletter in 2014, Hagerty reported. Since 2012 Zimmers have been eligible for judging by the Antique Automobile Club of America, in the class it opened that year for Second Generation collector vehicles.source 6source 13source 14
