Will these new blocks be added to the OEM Blocks or just 2” blocks ?
If just 2”s then what about OEM part, made from Cast Steel, usually little rusting and will not wear under most conditions and most JYs throw them out but they should be easily found in a JY.
If added to OEM, don’t do it !
Find another way, 2 - 2” blocks will add a lot of stress to the U-Blots and Springs, maybe even cracking springs and will be a b!tch to keep tight.
Also, I found that aluminum does not stand up very well.
The edges started to wear and crack and maybe it was just my U-Bolts (which I tightened all the time) but everything seemed loose every time I chkd it out; was not happy with the aluminum blocks… and I only used one of them.
