First time posting in this section, but I am doing an ls swap in my 72 K5 and wanted some opinions. There are three options for an engine crossmember that I have found.

1. Dirty Dingo
2. DIY4X
3. Tilden / Pacific fab (found out it is not LS compatible)

From what I see the DD is nice, but you have to completely rebuild the front brake lines. It looks like they would possibly be located outside the frame.
The other two look like they use the stock locations especially the Tilden which is an updated design. The downside to the Tilden is it doesn’t drop out for oil pan access. Not a deal breaker for me though.
I don’t have the ability to design and build my own so I’m stuck with these choices. Would like to see what people have experienced with these. Especially with header selection, brake lines and any issues. I am using a 4l80 with the tcase in the stock location. May have to move the engine crossmember to accommodate the extra length.
