Pilot Bushing
This should be an easy one. I'll be changing the clutch on my '79 L-48 this weekend. What size bolt do I need to pull the pilot bushing? I can't seem to find the info in my service manual (GM had a tool for it)
Also, the new pilot bushing that came with the clutch is not threaded. will this cause a problem (other than when I have to change the thing again)? Anything else I should look out for?

It should be smooth on the inside. Some guys will thread a large screw into the old one to pull it out. There is a tool for removing these, also the oldtimers will pack grease into the hole then drive a wood dowel in.
I've done all 3 and was easy.

I guess I was just getting confused with the whole oversized bolt thing. The owner of the vette shop in Des Moines ran through the process with me a while back, but that was monthes ago, and I forgot what size bolt to buy. This is the first time I've attempted this myself. Thanks for the info.

So I have everything basicaly back together. I had a heck of a time getting the new pilot bushing back in. It isn't in nearly as far as the old one, but certainly isn't going to fall out. Is this a problem? While the trans. is still out I want to make sure everything is set up ok.

Beater - I am in the middle of a automatic to 4 speed conversion and just installed the pilot bearing yesterday. I used an impact socket the same outer diameter of the bearing. I placed the socket over the bearing and hit the socket top-bottom-left-right until it bottomed out. There is a different sound when the bearing hits home.

Check these out. Sure beats all of the old methods of pulling bushings out. Cheap too!

I always smear the inside of the crank and the outside of the pilot bearing/bushing with antiseize.
I also "had" to invest in a snap on pilot bearing removar. Similar tool to a steering collumn dissasmebly tool. $85 or $130 I forget, but I can't use the hydralic or "bolt" method on an LS1 motor. They have a "hollow" crankshaft with a freezeplug in there.
