Hi John
Yes the later chev truck trans can be fitted.
you would require the later bell housing to suit preferrably the one with the horizontal engine mounts .
Starter , flywheel , handbrake and clutch are ok.
The later trans may butt against the rear of engine crossmember so this will require altering ( bending or cutting )
The trans is also longer so on 4wd this will require a back to back uni joint and on 2wd a shortened tailshaft.
There does not appear to be any problems with this conversion as the SM 420 is a very robust simple trans.
