I am going to replace the clutch in my 1984 FJ60 and I was set to use stock Toyota parts as I have had very good luck with them. They seem well made...like my Cruiser. However on a lot of the Cruiser websites and on-line store they advertise 'centerforce this ' and 'heavy duty that' and I am wondering if that route is advisable. No rock crawlin' work for my 60, just some mud, snow, sand and trail ruts to navigate. Would you folks care to comment on what you would recommend for my 60? Also I assume pilot bearing, throw-out, rear engine seal need to be replaced as well....thanks.
