Late Model 4020 Fender Mount Question

[ih555]

My tractor has 38" tires and also has the larger fenders. Do these larger fenders use the same mounting brackets as the regular 4020 fenders? And, do they use U-bolts or brackets and bolts? I'm trying to get it correct, mine has one homemade one and the other bracket seems a little large to me. What do the correct "police" think? Thanks in advance for your response!

They use same u bolt.There are a couple different stands with one being taller with more mounting holes.The 4320 used same but 4520/4620 had different ones and the fenders were the same but some had notches for batteries boxes.After 40 some years just do what you like.I personally like the smaller fenders up to 18.4x38.There were some that had 20.8x34s also but I think the 18.4x38 was only offered in 71/72.The ones I have seen with big fenders are usually 71/72s.
