I guess you found your bad lifter or more. I would probably look at the 5.9 magnum stuff to see if it can be modified to work. The lifters are probably the same and you can buy different length pushrods from Summit if need be. I forget what the V10 rocker assembly looks like. A pic would be nice. The bolt you may be able to get from ARP. Another alternative could be using adjustable pushrod guide plates and a stud kit to mount roller rockers on. The Chevy and Magnum stuff is real close and the chevy rockers work fine with a low lift cam. The Ford rockers are a tad longer I believe, like .030-.050" . So that is another thing to check. Of course you would need hardened pushrods with the guide plates. Crane also makes a conversion kit for the magnum with a guide plate and plastic insert for the pushrod to ride in. That may be anothe route for you.

488 Magnum Is the arm a 1.7 or 1.6 ratio? Either is easy to find in either chevy, ford or even magnum arms but they cost more. Just looking at the picture I don't see why the magnum pivot won't work but I can't compare them side by side. And you need to change your oil more often. The Crower kits come in either 1.6 or 1.7 ratio but are $1K and you still have to get studs and probably pushrods too. Not sure if those Crowers are for the Viper or truck engine and if there is a differance.

If the newer 01-03 rocker pivots are available you could re tap the holes to 3/8 and use the 01-03 pedestals and bolts the arms are the same. Drill and tap, I would want to pull the heads off for that. Besides the chance of getting cast iron bits in the engine it gets really cramped under that cowl.

The pivot pedestal for the 01-03 engine with the 3/8 rocker arm bolts are also dc'd.

Looking at that rocker arm comparison and the cylinder head cross section views I would be tempted to buy a couple different stud mount rocker arms and studs, singles of course an get an adjustable puhrod and play around with the pushrod length to see if something would work.

It appears the V8 rocker is too short to work. Those Crower rockers are self aligning so wouldn't need guide plates but pushrod length would be an unknown. New stock lifters should be fine.

Summit shows to have one of the Crower kits in stock. The 73657K for $1000. However they don't specifically list them for the truck engine and the application says it fits '92 - 2002 Dodge 8.0L V10, which tells me it's for the Viper engine. Will they work? Don't know.

Harland Sharp also makes rockers for the Viper engine but while it appears they will work with the correct stud (5/16 bottom and 3/8 top) they are not self aligning so pushrod guide plates and hardened pushrods would be needed. The stock Viper and truck engines appear to use the same rocker, probably why it's beefier than the V8 stuff. The Viper rocker arm kits use the 3/8 - 3/8 stud but you can buy the 5/16 - 3/8 studs separately. Same as would be used on a V8 Magnum. Pushrod length is on you to figure out. You need to replace the lifters and pushrods any way so just mock it up with the old parts and see how it fits before you buy pushrods. I loved my V10 truck and would like to build a 1st gen V10 truck but parts availability stops me. Good luck.
