Re: \'48 JD A transmission filler hole?
There is a forum for Vintage Tractors a little farther down the list. You might post there and get more information. If that doesn't work, try yesterdaystractors.com. That site is dedicated to antique tractors. There is a John Deere forum there where you can get pretty much any info you need on any old Deere. Or any other old tractor for that matter.
