Rad Support Bushings and washers?

Okay this seems really simple but... What washer goes where from the kit...?
I got this kit for the rad support for a 68 Chevelle. Has anyone used one similar?
It has all that I should need. But looking at the assembly manual there seems to be a couple of things missing and different. Figures right?

So this pic shows the manual's photo of how it should go together, in which order Etc.

I am not sure what a SPL. Washer is...It is the large one
This is what came in the kit and I set it up as I though it should be installed....?


What I am not sure about is the two vastly different washers provided.
The top rubber bushing has a metal top on it but I saw the manual says it should be a washer on top and so I put the smaller yet way thicker washer on the bottom thinking it should go in the frame for an easier fit?

Should it be the other way round with the smaller yet thicker one being on top and the wider larger on in the frame?

Or should I toss this and go with another Larger washer that was not provided but that I bought many years ago from GM for the car.


I know it seems trivial but with parts not being in the kit IE the But Spr. Thinking means Nut Spring to hold the bolt in top assembly...?
Guess I want to do things correctly and once not install and remove...
Thanks Guys and Gal for any help...
