Removing camshaft sprocket

4.0 Liter engine (Touring AWD model). I am working on removing the head. I can't find a tool to hold the sprocket from rotating. It seems like the best option is a 34mm offset wrench; which isn't easily obtained. I have seen some other camshaft holder tools on the market. I'm uncertain if the way they are designed is compatible with this type of sprocket. What are the best, most economical options?

There is a housing around the timing belt and pulleys. The cam comes through an opening in the housing so according to the procedure that I'm following you remove a plate from the backside of the head, remove the rockers, remove the cam sprocket and then push the cam a few inches out the back of the head in order to clear it from the encasement to lift off the head. Does that seem right? I have a 33mm wrench and that seemed just a tiny amount too small. I borrowed a 36mm clutch fan wrench and that seemed quite a bit too big but I did get a decent grip on it a couple of times but couldn't get it to budge. I started to worry maybe reverse threaded? I have a terrible habit of breaking bolts; so I worry. I'm following a Chilton procedure that I found online through our public library database system. It is professional oriented -- gives the procedure with no detail or explanation. I would think it would at least note, however if it's reverse threaded, unless they're ALWAYS reversed. I ordered a 34mm wrench online; I can't find anything close by. I am going to put the timing belt back on. Then I should be able to hold the crankshaft bolt or have someone else hold it while I try to torque those cam bolts off. Does that make sense? Sorry to seem like I'm answering my own question but really any professional insights are welcome.
