Well I have no where near 60 Massey's but I did pull the fronts off a 44 and 30 standard at the same salvage yard. Both had the larger hubs, but the axles and pivots were different. The 44 standard axle went under my 55 puller with some widening, and the 30 went under the one in the photo below... The only standards at the house to compare to now are a stock 55, the 44 Diesel and a 101jr so I cant really even compare originals side to side. Just going off my memories from 10 years ago or so when we did the original swaps.
Have 17 different Massey Harris' here. 9 of those are 44's and there is a staggering amount of subtle differences just in those 9 tractors. What I'm trying to say is, not calling anyone a liar, just not surprised by any thing I find on these old tractors.
