Replacing flywheel/flexplate

I am purchasing a Pioneer Heavy Duty Flexplate to replace the cracked/broken one on my '97 Blazer 4.3L AWD 4L60E. The original flexplate totally seperated leaving the small section bolted to the crankshaft and the larger section with ring gear bolted to the torque converter.
Aside from the proper torque requirements when attaching the replacement flexplate, are there any orientation requirements I need to be aware of with respect to the crankshaft?

TIA

you said flex plate, but then 4l60e, is this a ring gear your doing???

the parts books refer to the flywheel on the automatic transmission as a flexplate and not a flywheel so ... I am replacing the entire flywheel/flexplate as the original has cracked and seperated leaving only a small section bolted to the crankshaft.
