3.2 flywheel/pulley/crank balance

Bought 3.2 engine from Thesis. Same internals like GTA engine, only camshafts different. Have 3.2 cams already.
Problem is that Thesis use automatic GB. And no flywheel as in other V6.....
Should i get any V6 flywheel with or without crankshaft pulley(have one from Thesis and my existing combo from 3.0 V6), and bolted onto 3.2???
I would like to balance all 3 pieces together, but not such service in my country.
When i upgrade my 2.5V6 to 3.0V6 i just bolted old pulley and FW to 3.0 engine and almost 4 years of trackdays only, still no problems. Lucky maybe???

If it helps I have some brand new GTA flywheels in stock.

If you have a 3.2 engine, 3.2 front pulley & 3.2 flywheel then even if they all came from different engines they'll be reasonably well balanced (you can see factory balancing marks sometimes). But it is better to strip the engine and get the bottom end rebalanced especially if it is for a track car which is going to see continuous hard use.

havent done mine yet as other things have cropped up.. but balancing needs bob weights made up to weight the crank..

so as Pud says 3.2 crank 3.2 pulleys ( as different to 3.0 litre item ) 3.2 flywheel as some 3.0 litre items only have a single set of holes for the clutch cover where as 3.2 have twin sets iirc
