Maybe this has been asked or discussed before but I haven't found an answer to it yet. I was doing some work on my distributor today and I am wondering if there is any reason I cannot replace my grease cap with a grease zerk? My cap is not in the best shape and I cant think of a reason a grease zerk wouldn't work instead of tracking down the specific cap for it. I am assuming you give the cap a turn every so many miles to push a little grease into the shaft and then refill it every 5000 miles. I could just break out the grease gun every so many miles and give it half a shot. Or is there something I am not considering here?

Thanks
