I run antique plates on mine
it says I have to have an original chassie ,motor and body
all 3 of mine are original 1967 parts it didnet say they had to match the serial #
I have been running them for some time now and pretty much drive every weekend where ever I want with no problems
your right as texas is pretty lax
as a matter of fact mine is an 8 year plate
I dont dive it during the week too much
I have never been pulled over YET
most of the times get a nod or a thumbs up
I try not to look at the COPS EVER
its all comon sence realy, if you act like an idiot expect to get pulled over.
also on basic Classic inspections you can just do away with the holes all together if you are doing your own glass work
say it never came with wipers and they will pass it
mine had a hole so it had to have wipers
now back to the wipers
a stock late model 12V system should fit under the dash with a stock spedo no problem
got one if ya need it
where you run into poblems is too many gauges in that area
the wiring and such gets in the way
I didnot find that out untill it was too late
let us know how it goes
