Pitman arm question

I have recently purchased an original quick ratio manual steering box for my 69 Roadrunner, in order to convert from power to manual. Is there are specific 'quick-ratio' pitman arm required for this box or will a standard pitman arm for my car be OK to fit to this box?

Thanks

I think the T/A-AARs had both a different pitman and idler as well. Can't go short on one without doing both.
