This might be one of those "everybody knew but me" things, but this is my first time tearing into the 4L SOHC engine and I noticed a few things that might be useful:
In the picture below, bolts A are M12-1.75 x 120mm that I bought for the two bed bolts closest to the cab, I noticed that the (used) head bolts B (T55 Torx) are the same size and thread pitch, just a little longer (10 or 15mm, abt 130mm total) with a big washer would make good bed bolts, (all mine were rusted/ mangled purdy bad) they're threaded far enough to use in all six places on the bed if you managed to save all the "J type" cage nuts C.
The other two bolts are D, a harmonic damper bolt, (hex head, 72mm long) and E, a front jackshaft bolt (Rev Torx head, 92mm long) They're both M12-1.5 thread, the jackshaft bolt is longer then the damper bolt which makes it handy to get the harmonic crank balancer started on. It will draw the balancer more than half way on before bottoming out, at which point you can swap in the proper bolt and torque to spec.
Hope someone finds this info useful!!
