I want to use these older plugs on upcoming striper fishing trips, all of these are probably 25+ years old and hooks are rusty or dull. Where can I buy replacement hooks and any tips to ensure I am getting the right size? Stores near me would only have bass sized treble hooks and these are much bigger.

 

Here is a chart you might be able to verify what size you might need.

With the striper population taking a hard hit on the East coast, its best to use single replacements when possible, or at least swap the rear treble out for a single.  They dont beat the plugs up, have a better landing ratio and are safer for both you and the bass.  The drawback is that some swimming plugs, especially the older ones that were designed to be used with open eye trebles wont swim right.  The loss of resistance causes some plugs (mostly lipped swimming plugs and possibly darters) to have a tighter action. 

 

Some of the older plugs designed to use open eye hooks (instead of split rings and a closed eye hook) wont work properly with the added weight of split rings.  It looks like only 1 of those plugs may require open eye hooks.

 

VMC  4x perma steel O Shaughnessys are the best bang for the buck.  If you can find older stock you should be able to get 25 of them for about 8$.  I would recommend 2/0 as it fits the standard size plug like a 6" 7/8oz bomber or 6" 7/8-1 1/4oz SP very well.  You could bump up to 3/0 if you wanted too, but the 2/0 work fine for me.  Since the VMC are very cheap you could buy a 6 pack od each which would run you about 5$ in total.  Then order more of the size that you feel would work best.

 

As for single replacements the VMC Coastal Black 4x in 2/0-3/0 would work for plugs and tins as well.    

I usually take the lures to a good bait and tackle shop and match them up. Around here most shops stock hooks for big plugs because Striper fishing is popular. If you are near coastal Virginia you should be able to find a shop with the hooks you need.
