65 radiators are more narrow. I'd have to measure by how much exactly. I'd imagine you'd want something with at least 3 cores though to keep everything cool.
I did the same with mine, though I angled it into the corner so a filter would fit nicely and also get a little bit of cold air into it from where the battery cooling duct used to live. I ran the turbo outlet through the inner fender, gives a perfect route to the intercooler, looks like you're planning to do the same?
You've got some subframe connectors going in too right? That's going to be a crazy fast car.

Cold side pipe looks a little close to the belts, I brought mine in through the driver's inner fender instead. A compact IC sits perfectly in a II (even with an AC condenser), seems like it was made for it.
I've got a '68 radiator in my '75, it's BARELY adequate, if I get caught in bad traffic in the summer (Texas) it'll hit 230 or so while sitting at a light it is the single-core light-duty for a 302 though, if I'd gone 3-core it would probably be fine.
I'm glad to finally see someone doing an LS-family swap. I said repeatedly in the three years I owned my '99 Sierra that if the truck ever got totalled the 4.8 and the 4L60E were going in the II. Fortunately that never happened (totalling it). But it would've been damned cool having that engine in the II.
