Those Marlin low profile magnetic diff drain plug are they the same size as the fill plugs, I'm gonna replace the diff gear oil but I don't want to take one drain plug out and see if they are before repalacing gear oil. If there not the same size then I'll just order 2. One more question is the manual trans drain and fill plug the same as the drain plug on diffs. If so I'll get more for those 2 if there the same size. Where can I get a magnetic oil pan drain plug on-line?
Thanks for any info...

 

Yes, same size as fill plugs and the t-case fill and drain plugs as well, at least on my '85 they are. Not sure on the tranny fill and drain plugs, you would need to check.
