Stuck distributor gear 318la

Well looks like I'm going to have to do as suggested above, fill the filter aand hope for the best short of dynamite this gear is not coming out, I've tried all the ways mentioned above and as mentioned I'm working blind as the distributor hole is under the over hang of the fire wall ...so frustrating! Well, I sure hope it's going to make op at least I got a mechanical gauge to varify.
