cabs. will it fit ?
Posted: March 4, 2007, 7:39 pm
lots of questions about the differences in 61-66 cabs and sheet metal as to what fits what and the differences.
if you happen to find a cheap truck with a good cab or are planning a cab swap this will help to know if it will work.
i will start with the standard cabs f100-f600. the body code on the VIN tags for these is 81.
any 61-64 cabs will fit on any 61-64 frame.
any 65-66 cabs with stepwells will also fit on any 61-64 frames,and any 61-64 cabs with stepwells will fit on 65-66 frames that have cabs with stepwells.
those frames are 65 f100 4x4, 65-66 f250 4x4, f350,f500 and f600.
however that is only mounting and does not take into account the following differences which are year and type specific.
they are:
the 61 and 62 cabs have a different stepwell bottom,and the ribs are longer than the 63-up.same thing with the outboard indentations on the cab rear.61 and 62 are shorter.
63 and up have drain holes at the lower front door jamb.
64 and up have a higher roof.
65-66 have different vents on the kickpanels
all 4x4 and F350,500,and 600 have a hole and cover on the passenger floor for the battery, except the 66 f100 4x4.it uses a 65-66 2wd cab.
f350,f500 and f600 cabs have a different pedal bracket and different holes for the master cylinder.the f100/250 2wd and f250 4x4 brackets can be made to work with these cabs as well as the master cylinders with some slight modifications.if you plan on keeping the single bowl master cylinder it does not matter, you can just get a brake line adaptor and hook up the brake line.
65/66 f100 and f250 2wd and 66 f100 4x4 cabs will only fit on 65/66 f100/ f250 2wd and 66 f100 4x4 frames.
long wheelbase integral (unibody) cabs\beds will fit on any 61-63 lwb 2wd frame and any 61-66 f250 4x4 frame.you will need to add spacers to some of the wood blocks on the bottom of the bed for the 4x4 frame as the frame is flat with no rise over the rear axle.The code for these cabs is 66.
short unis will fit on any shortbed frame

it has been proven that separate uni beds can be done as well as to graft the uni bed onto a standard cab truck

the 65-66 f100/250 2wd and 66 f100 4x4 cab will also bolt up to any f100/250/350 2wd or 4x4 frame from 67-79.
the above is meant as a guide if you happen to be needing a cab and do not wish to do much extra work, anything can be made to fit with modifications of frame and cab mounts if you have the time and tools.
