looking for a 603 flywheel lock tool
 

Can any one help me please?
I am looking to borrow/rent/buy a flywheel locking tool for the OM603. I have let gravity overpower me and a small fastener has fallen down onto the crank sprocket of the timing chain (while replacing my 87 300 D cracked 14 series head). I have removed everything else except the Harmonic Balancer, to access the timing cover. I already have over $3400 into this head replacement job and would rather not go the $173 from Samstag to use it once. If someone has this tool please contact me to work something out so that I might use/rent it for a few days.
