Yes. they do come in different heights. Once removed the height should be marked on the bottom. I have many front sight blades. Most are 5,3 or 5,4 marked. I have only one 6,1 marked blade. The K98 is zero set at 200 meters so anything less than that and you will need to adjust by eye or change the front sight to a taller version. Gun shows are a great find for front sight blades as most keep assorted parts in bins or cigar boxes and so forth. The blades settle to the bottom and get little attention. Each time I hit a show I find a good half dozen of them or more if I want them. Most every waffen marked one I have is e/37 marked. I see very few with other proofs.
Talk is cheap because supply always exceeds demand.
