You CAN make your own timing pins, people on these forums have done it.
You can also go over Niagara Falls in a barrel, people have done that too....
You can get your very own set of Sealey tools for $120 shipped brand new in the box from Great Britain, it's Sealey VSE5056.
Google that and you'll find the whole set with VM.1052, VM.1053, and VM.1089 as well as the tensioning wrench for the tensioner and 2 other tools you will probably never use.
If you are taking the cam gears off, I wouldn't personally do it with anything but the VM.1085.
I bought one from a member here because the online prices are redonkulous, but there are a lot of places/people that rent them, and I would strongly advise you use it (Remember the Barrel?).
Listed Miller tools:

Thtat's $109 right there without shipping and that doesn't include the tensioner wrench or a nice abs plastic case for it all....
Whatever you do, good luck!
