Gem Master Cylinder

If anyone is interested for the early year gems a substitute Master cylinder for your cart is a 1987 dodge charger its cost around 23 bucks. you will have to change the brake line ends to metric or standard don’t remember which but it is a direct bolt on. or use adapters I changed mine and re flanged the lines

What’s the bore size?

Are you sure of the year ? I got one and it was too long.
