Are FJ45 & HJ47 clutches interchangeable?

I've got a FJ45 1981 that's had a 2H transplant before I bought it. I pulled out the clutch today & it's stuffed, the driven plate has hard rubber cylinders instead of cushion springs, one of which had been torn out preventing the clutch from disengaging. Can some one tell me if this is a FJ45 or a HJ47 clutch & whether they are interchangeable:?:

yes they will interchange, the 6 cylinder engines use the same clutch dimensions and coarse input shaft spline.
the toyota factory clutches and some aftermarket use rubber blocks instead of springs in the clutch driven plate to provide allegedly quieter, better damped engagement. and reduced on/off throttle harshness.

The bloke down at Autopro here today reckons they aren't interchangeable because of a different bolt pattern on the flywheel, I took his word for it, hope the fj clutch isn't weaker than the hj

hrm.. he could be right but I'd swear I've interchanged the two before.
if there is a difference in clamping pressure, the FJ will be stronger, the 2F makes 30 or 40 more peak Nm than the 2H

when i was looking at doing mine, i was told they were different, and the cataloge shows a diff part number between the diesel anad petrol clutches

I picked up the clutch today its a FJ one made by Daikin hope the petrol ones are stronger, cost me $251. Looks like no play this weekend.
