Hi All,

A quick spot of reassuance required!.
I have bought a pair of top hats from GTS to go into the top of my Granada front uprights, but they are way too small in diameter. I was under the impression that sierra suspension carrier holes were the same diameter as granada ones, but I am obviouslt wrong. But what diameter are the sierra holes?.
Cheers
Adam

Not sure which measurement you want but..

Stud spacing is 4x4.25(108mm), and they are 0.5 inch studs.

The center is 2.51 inches (give or take and the hub diameter is 5.16 inches

think he means the big hole in the top where the struts clamps in, where the king pin modification goes.
sory, dont have sierra uprights or id meaure em!

it appears to be 46mm unclamped. If it helps, i have 4 spare sierra assemblies, including 240mm discs and calipers

thanks all,

Looks like I will be making some specially for my hubs, then!. Easier than changing both front hubs and rear half shafts, probably cheaper too.
