Question Small Block Chevy 400 flexplate install

Replacing a flexplate on 400 chevy (external balance.) Unfortunately, forgot orientation of counterweight on original flexplate and there are no dowel pin on crankshaft to orient new one. Arrgh Sooo, which way does the flexplate go on?
In other words, does the counter weight on the flexplate align with counterwieght on crank? In this orientation, if the counterwieght on the damper in front was at 12 o'clock, counterwieght on flexplate would be like 6 o'clock. Or, does counterweight on flexplate go in same position as balancer? 12 o'clock balancer, 12 o'clock flexplate?
Hope this makes sense, or someone can give a better answer.

Thanks for all your help!

Since the dowel pin is absent, it goes inbetween the 2 holes on the counter weight side, you should see the hole for the dowel pin in the crank and on the flexplate, it`ll be the hole inbetween the 2, and lastly, the hole shouldn`t be treaded. good Luck.

I have seen this question asked before and I'll say this, It is impossible to install it wrong. All six bolts will only line up one way. You can take all the bolts out and rotate the flex plate 180 degrees it won't line up, it won't line up 90 degrees out, it WILL ONLY LINE UP ONE WAY.
