Squaring cab on frame

[64chevmn]

I put my cab back on the frame last week and plan to start hanging the doors and fenders soon. Is there an easy way to square the cab to make sure it is sitting on the frame in the right spot; or is there enough adjustments on the fenders to compensate if the cab is too for forward or too far to one side? All the body bushing and core support bushings are new if that makes a difference.

Your only going to have so much room on the cab front to rear and right to left.to center the cab right to left on the frame is on measure from a common point on the body like the inner rocker at rear cab mount to the frame on both sides and equal them do the same for the front of the cab. That should get yo even right to left. Front to rear u may not know a lot till u get the radiator support and fenders on but if I'm not mistaken there may not be much front to back. This is a start. Hope it helps

I cross measured mine. Take a common reference point on both sides of the cab, drivers side to front pint of passenger frame and vice versa. If that measurement is exactly the same then you are squared .

I normally measured from the cowl seam edges on both side of the cab to the far edge of the frame end.
