Just curious why you want to run ls1 injectors? You can buy non marine 8.1 injectors on eBay pretty cheep and no spacers or adapter would be required. You will also need a refund with any injector swap.

Ya its basically 5/8, I can mic one of my old spacers if needed. Let me know.

No ****, how about that. I remember when I was doing mine no one made them and I found it hard to believe. Thats good someone finally started. From what I recall the issue was obtaining the Female Multec II connector to make the adapters.

It appears that if you want injectors over 42#, then you aren't going to be able to find a drop in set for this truck, at least not for a reasonable price. Big LS1 injectors are up for sale daily on LS1tech.
