Help with shocks on a 66 needed

[msg]

I bought some Belltech shocks after talking with the tech guy I told him I had a stock-non lowered c10 and wanted to get a front a rear shock set. So he said this was the right set I needed

But there a few things Im unsure about on the front. Is the top portion too wide in diameter? Seems like it will bind.

The other issue is that there were some weld blobs on the frame that I dont understand. I was planning on grinding these off and maybe having to return this set of shocks. Just wondered if anyone else ran into this before.
