Do I go for the complete 489 center or just a brand new sure grip?

What more can you tell me about this case. I must have been missinformed. Is it the axakt same case as a 741, only older, does it have another name? Will i find parts for it if needed etc...

Thanks

there is no reason to run it... i have a spare 742 if u want but why waste money on a 50's center, just go a 42 or 89 and be done
