Hey Everyone-

I'm a 200-Series guy building out for a GFC RTT and I'm planning to adapt the GFC 5th Gen 4Runner direct-mount bracket to my LC's OEM roof points. The geometry is great - bolts straight to factory points, no crossbars, lowest possible stack height.

Problem: GFC doesn't publish the bracket's dimensions, and Toyota's body drawings are paywalled. I've searched everywhere I can think of (Prinsu, Gobi, Sherpa, Gamiviti install guides - none give dimensions, just "line up with the holes").

If anyone with a 5th Gen 4Runner is willing to pop the four black plastic covers on the roof and pull out a tape measure (or has another way to get these measurements), I'd be hugely grateful for two numbers:

1. Fore-aft span between the two OEM mount points on one side (front mount to rear mount, center-to-center of the large bolt) - I have one DIY source saying ~50.9" but want to verify

2. Bolt-pair X spacing on a single mount pad- distance between the two small bolt heads on one mount (center-to-center). For reference, on the 200-Series LC it's 2-1/8".

Why the 4Runner mount specifically:


I'm chasing the lowest possible tent height for CoG reasons, and the 4Runner bracket bolts directly to OEM points - no crossbars, no platform. That direct-mount approach keeps the tent flush in a way that universal mounts and platform racks (Prinsu, K9, Slimline II) can't quite match because of the crossbar stack underneath. Dissent's rack isn't as offensive from a height standpoint(still a bit higher than this concept) but I'm seeing 4-6 month lead times.

All those other options are great in plenty of builds - just optimizing for stack height on this one.

A quick phone pic with a tape measure would be perfect. Happy to return the favor with any LC dimensions if you ever need them.

Thanks.

Tanner
