There are other considerations too...
Depending on where you mount that puck, may also require a type of connection point change too...
What am I talking about?
SO-239 to PL-259 - that type of connector you see on a typical mirror mount is straight thru and perhaps the best "less fooling around with" connection you'll ever have to deal with. MNO mounts are that less fiddly way also but come with fewer/less options...Stick it on and hope like h*ll it won't break the connection when you hit an overhead object - or worse - rain can start leaking into the connection and cab, ruining your Interior and SWR at the same time.
- Would be a good idea to buy some sheet metal to help with the reinforcement so you don't have to not only committing to holes in the cab, the replacement cost to upgrade to the sunroof option having to be added in because of the rust and weakened mess the flexing from your hi-po miracle of an antenna, caused.
The Breedlove mounts though, if you look at their setups, - come with SO-239 (the Female screw on end) the pass thru-style of 180. OR of another type that many HAVE to use due to clearance in the pass-thru (Bulkhead-design referring to "bulkhead" as your Finish metal and vehicles outer skin) - what they call "stud-mount" being what it is, the coax you use has a PL-259 on one end and has two ring lugs soldered to the opposite end of the coax that goes at the antenna - then the CENTER lug is bolted to the main STUD that passes thru into the antenna and the SHIELD side lug goes to a convenient ground point a VERY short distance away.(shorter the better)
There are other mounts that you don't have to cut and chew up your coax and will handle some loading of an antenna - I just cannot Guarantee they will last - are "puck base" types that feed thru but are 90 degrees off to the side - with an SO-239 to help keep the coax connector aspect simpler, and the lug ring problems of corrosion and impedance bumps out of the hassle with tuning and install...

(can find a plethora of these on eBay)
A word of caution on those 90 degree right-angle mounts - they don't tolerate large whip antennas very well, best to use them for 4 foot or less - they have a right angle tap "weld" the joins the stud for the antenna to the SO-239 - which can break and leave you with SWR issues - so you have been warned...(Personal Experience)
When dealing with close quarters and headliner esoteric's, keep in mind that the Stud-Mount to Ring Lug, may be the best if not, ONLY option you can use to still make the system functional.
So use a good puck mount and plenty of backing plate material - SAW Blade or otherwise - to help reinforce the mount so that when you can't avoid the overhead strike of limbs or ATM clearance issues, you can have the antenna survive the mess and keep going.
