S10 Swap how to

[frankist]

Quick question -
I have a 49 gmc long bed, but after searching, Im afraid I have a later (year) cab due to having shackles holding the cab in the rears.

By having the shackles I opted not to use the bushing to fit in between the c brace which runs underneath the cab, but instead welding a 4x4 1/4 plate on the c brace. Ive got the cab on the frame and it looks great, but am wondering if the bottom line of the cab should run parallel with the frame?

It looks raked to me by about 2 inches too tall on the rear. Ive used version one cab mount designs, and am utilizing stock s10 body mounts.

If anyone has a picture of their cab on frame it would be very appreciative. Or if someone can check on their finished build whether or not the cab rest on a parallel line with respect to the frame. Thanks guys.
