4.0 stroker flex plate issue for instal

[98zjstroker]

So I was getting ready to throw my 4.0 stroker motor in today. While trying to bolt my flex plate to the crank I realized the bolt holes do not lineup. The 4.2 crank came out of an 87 And a 4.0 motor is a 98 ZJ. I have the 42RE automatic tranny. Not sure if I need to replace the flex plate or what. Haven't seen anything about this in the stroker builds can someone please help.

If I get the new flex plate will it still bolt on to the 90ﾟ bolts on my torque converter and if so which new flex plate do I need

The bolt holes are asymmetrical on AMC engines.
Rotate the flexplate around and you'll find they line up.
