Are the trans to block plates interchangeable?

My guess would be that it's primarily to shield the bellhousing from debris as well. I think I'll be ok as the newer one has more clearance than the older one.

Here is the newer plate laid over the older plate.

If you have a 4 bolt motor, it's a moot point... The older version wouldn't fit.

its just a dust shield, there are a few gaps it fills, without it debris could get in the bell housing

Yeah I have a 4 bolt. So the earlier one won't fit on a 4 bolt? Would the later one fit on a 2 bolt?
