GM 340278 clutch fork replacement

[my kids took the truck]

Any advice on replacement clutch forks (0.795 FORK ASM., Clutch Release) part# GM 340278-1

there are a few replacement sources--I won't list them

1974 K5 with the SM465 and original bell housing and clutch pedal assembly (nonhydraulic)

also, advice on

• throwout bearing
• clutch pivot ball
• offset bellhousing pins

all this is going to a shop but they want me to bring the parts

doing my homework, what else is on CK5 and elsewhere

• zero on CK5 specifically PN 340278
• most of the CK5 posts on clutch fork are related to NV swaps
• nice informational here on part numbers https://4speedconversions-com.3dcartstores.com/340278.html
• some random discussion on clutch arms here https://nastyz28.com/threads/67-72-clutch-fork-vs-72-and-later.247070/
• a few used ones on eBay for $30

Background:

• Back in 2018, I'd posted about puncturing the pushrod pan on my clutch fork https://ck5.com/forums/threads/push-rod-punctured-pan-on-clutch-arm.334162/#post-3888632
• I'd purchased a new OEM clutch fork but it was in the back of my blazer when someone broke out the glass and helped themself https://ck5.com/forums/threads/k5-rear-glass-no-tint-74.342932/#post-4186107

Sorry I am no help on new parts, I always have a few extra used parts and I posted in your other thread how I made a new rod

back when the problem first showed up seven years ago: my father-in-law thought the carriage bolt approach was the way to go (I bought one and had it all ready) and I thought the brass acorn nut approach was the way to go--he was right
everything is getting taken apart for the throwout bearing so I'm having everything rebuilt from the rear oil seal to the driveshafts including transmission and transfer case: made it 45+ years how it is so it will last forever going forward given how few miles go on this K5 now
