G’day, I’ve got a 1967 Fj with a Holden 253 in it and I would like to swap out the 253 for a 12ht. I was just wondering what could be involved thanks!

Has anyone done this conversion? Does toyota have a bellhousing that will fit the 2h block from the h150 or h151f? The old h55f just isnt up to scratch, never has been. Looking for a better box for a custom 75 series build. Thanks

Hello all, I’m new here and new to my cruiser in general. Just got a 1989 HJ61 RHD turbo diesel 12HT and am needing to learn more.
