727 Tailshaft bushing

Hi Folks!

Just bought a seal and bushing kit from a local parts store. I see the bushing has a longitudinal seam due to the roll forming process. Is this OK for a performance 727? Is there a manufacturer that offers this bushing seamless? The seam would be on the bottom of the transmission away from the fluid feed channels. Non of the manufacturers elaborate on how they make theirs. Thanks!!!
