This restoration was not sponsored, but I have listed sources here for those who may be taking on a similar Tiger or Alpine project.
Gary at Vintage LEDs makes some LED panels for the Sunbeam Alpine and Tiger.
The California Association of Tiger Owners (C.A.T). is a club dedicated to the preservation of these rare cars. The club manufacturers some parts and provides forums, newsletters, and tech-tips that are invaluable to anyone taking on a Sunbeam project.
Rick at Sunbeam Specialties has supplied many chrome, rubber, and trim parts.
Dale Akuszewski provided suspension goodies and technical advice.
Sunbeam Alpine/Tiger Spares in the U.K. provided chrome parts.
Autosport setup the limited slip and 3.31:1 gears.
CG Autowood supplied the original style burled walnut veneer dash.
Jim in Vancouver supplied updated electronic gauges that look like the originals.
Jeremy at Rebel Wire supplied a modern wiring harness with proper fuses and relays.
Modern Driveline supplied the TKO600 transmission and associated parts and modifications necessary to fit the Sunbeam Tiger.
Note: Even after providing engine information, I was sent the wrong clutch and had to pay cross country shipping 3 times on these heavy parts. Modern Driveline doesn't make mistakes, yet I somehow ended up with two driveshafts. Check your order before and after delivery!
