71379952 is the kit to make prior to 98 heads; prior to 21000 sn, fit late lateral tilt. Cutting and welding required, but it is a neat finished product that will fit lat tilt. Kit is less than $1500 best I remember - two men , half day labor with torch and welder. We have done a couple, second one took lot less time as we didn't have to argue over instructions

. All corn heads heads after 21000 will fit either lat tilt and non tilt on all with top and side adjustments.
