I'm currently looking at a 1989 FJ62. It is an import from Columbia but currently has a clean US registration. It has the F3 engine and the owner says the front brakes are drum. Did they all come with drum brakes? Are there any conversions available to make the front end disc brake? This F3 is carbureted. In know the F3E is injected. Anything that I should be aware of? Thanks for your help and pearls of wisdom.
