Lowering block Questions.
First off, my heynes manuel doesn't look anything like what I have on my car, is that normal???
I took apart my U-bolts and I am trying to figure out a good way to lower my car by one inch. I see 3 options.
1. I have a custom pieces made that fit perfectly between these two pieces. Probably cost me 150-300$ for 2 custom blocks at my local machine shop. Aluminium with a recess on one side and a bump on the other to fit the Oblong shape.
2. I grind down the lump on the piece in the picture below and buy this block from summit:

It's dirt cheap, but will it move around on me and do weird things to my
suspension and alignment? The pin in 9/16 and the hole in the differential casing is over 1 inch and oblong shape. There would be nothing centering it from underneath ether, just the ubolts and the weight of the car.
3. This is my least favorite, but looks like it's the way people are doing it? Remove the piece that covers the spring and insert that lowering block from summit directly between the leaf spring and the differential casing flange. The aluminium block would be directly impacted from the springs movement and I'm afraid it might break? (Looks kind of week to begin with, extruded aluminium I'm guessing?) That pin in the leaf spring would hold it in place tho. Like in a sandwich between the pieces in this photo:
In option 3, like the next photo, what stops the differential and the whole u-bolt assembly from sliding forward and backwards on the spring say 1 inch in any direction? (The pin from the block has that much play in the differential casing flange hole) Could that mess up my alignment at every bump in the road?
Well I hope I was clear in my question, it's difficult to explain what I want to know, let me know if it is unclear pls. Is there a better way of doing it?
