GMC 3/4 cab mounts the same as 1/2 Chevy?

[siggyfreud]

Hey all,

Looking to purchase some new cab mounts for my 66 GMC 3/4 Ton. Looks at mounts readily available online, they appear to be for the 63-66 Chevy 1/2 ton, and 3/4 ton have different frame mounts thus they take different mounting hardware. However, from looking at photos my rear cab mounts appear to be the same as the 1/2 style, which made me wonder if the GMCs used the 1/2 mounts across their range.



In that photo you can see what my rear mounts look like. Would I be good to go with the standard 1/2 mount kit?

Cheers all!
