Boyd had a smiliar tool for the inner axle seals. Made installing them very easy. I'd get it. If I thought I'd ever run into you, I'd ask you buy a second one for me, reimburse you and split the shipping costs! Bearings and races are as stated above a brass drift job unless you've got a press. Mike and I did ours together as rookies under the guidance of Boydmick. I think we were both tink, tink, tink on side one and BAM, BAM BAM on side two once we learned that there was no way a brass drift was going to damage anything!
