You can make your own using thin rods from Home Depot. Use search for the correct diameter size- I always forget.
I believe Thunder sells the actual JPR rods.

Make your own. My bound up in the motor and it was a huge pain in the ***, I had to file them down to get them to work right. From what I've heard, it's happened to other people too.

i used 3/16 metal dowels from the depot, just cut them a little over the length of the cam and marked a line to know it would be in all the way.

3/16's is too small. People tried that before and had a lifter slide past. 5/16's is the smallest you can go and still be safe. I tried to use metal rods like the JRP tool, and even after extensive grinding the passenger's side still didn't slide in. It was really bound up good. Tried the wooden dowels and it went in easy as pie.

I've heard wood is the best because the holes aren't in a straight line, but I was REALLY scared the wood might break off inside the engine. What a bitch that would be to get out.

considering the fact that dropping a lifter probably requires another 9 hours of work to get it back to its rightful place, isn't it worth the effort to use a dowel?

My wooden ones cost I think $1.17 a piece, and gave me excellent piece of mind.

I said screw it and bought the actual tools about 2 years ago, and they have served me well several times. About to use them again, this time on the Vette. I don't want to deal with broken wooden sticks, or lifters sliding past rods that are too small.

As easy as the wood ones slide in ya would have to be a tard to break them and they a hard hard pieces for wood! I always sand them down to make em extra slick!

The wood ones work just fine. There really isn't anything that can cause them to break, they just slide in and out.
