installing lowering blocks

[65chevysub]

I am having some lowering blocks made from thick wall 2" tubing to use as lowering blocks for my 65 Suburban 2 wheel drive. I pm'd a member on the 60-66 truck forum but thought I would ask here as well. Does anyone have any pics showing the install of the blocks using a floor jack(if possible). I'll be doing this in my driveway which is dirt.
Can anyone help with this request? Even just text instructions would be helpful.
Thanks

Here is the readers digest version.
1. Get the longer ubolts from way2lo here on the board.
2. Jack the truck up and put in on jackstands, with the jack stands on plywood.
3. let the rear down and pull the wheels.
4. with some pressure on the jack under the center of the rear end pull the shocks loose at the bottom.
5. Let the read down so it is hanging on the springs.
6. If it has the original ubolts take a grinder or a sawsall and cut it off on one side.
7. Drive the stubs out the trailing arm to get it out and the shock plate off the bottom.
8. drop one of the new ubolts through to hold the rear in place and do the other side same as the first one.
9. now you can raise the rear up a bit with the jack and slide the ubolt up one at a time and put the blocks in and put the shock plate back one.
10. once both sides are together then tighten it all up and put the shocks and wheels on.
11. never put you self in a position where the truck can get you if you have a problem with the soft dirt driveway.

Thanks PGSigns.
Sounds simple enough and I wont put myself in any danger. I have so e 4x8 sheets of 3/4" plywood to put on the ground if needed.
Thanks for the fast reply.
I will check with way2low about the bolts

pgsigns did a great list but concerning #6 I'd like to add that if the nuts are rusty and won't come off and you do cut the old ubolts they will make one heck of a popping noise when they let go. Just don't bang your head on anything or be surprised when it happens. I found out the hard way...

Good luck, Rg

A full sheet under it will help a lot. Here is the link to the u bolts.

Thanks guys. I got enough knots on my head already so dont want any more. One last question. The metal shop called me and wanted to know what size holes to drill in my blocks for the bolts. Can you tell me what size so I can pass it on to them?
Thanks bunches

They should be 9/16" to 5/8".
