930 flares on a 964?

[Tbone425]

Anyone here been through this... I have 930 flares I want to weld on and it looks to have some shape differences. I know the bottom door sides will need modification... but it looks to be a slightly different shape opening. When the 930 flare is where it should be the opening lip comes down a bit further at the top to about the 2:00 position. Anyone else experience this?

Thanks!
