Around 1970 I became interested and soon became expert in Rovers; seemingly one of the few who were. I was one of the few who rebuilt rear calipers on 2000 and 3500S P6. I built up this box of rear caliper spare parts, as even 40 years ago NO parts were available. I no longer own a Rover, so am selling this Rare box of parts. If you own or repair 2000 and 3500S, Buy this box while it is still available. One day you will be Very grateful you did. I have  many other  Rover parts, including  body panels; and hundreds of parts for all British cars 1950-1994, on my eBay store.. They are  arranged in 20 categories. If you don't see what you need, please ASK., and I will put it in the store for you..  Please inquire 1954JAGUARS  or  1 954 JAGPART, .. I have compulsively hoarded parts for 40 years years;  But have moved them to SEBRING, the Heart of Old  FLORIDA. I have the largest stock of  original Old English parts in the colonies, including Many Rover parts.. I also give free restoration advice, and am VERY knowledgeable of Rovers. .Please inquire.
