Propane from the Factory?

[70chevytruck]

Looked at this truck today....never realized they had propane option from the factory. He converted it over to fuel but still has the propane carb (is that what you call it?) and all the underhood stuff.

Truck was bought in California but never had a title....what does it take in Texas to get a title? I have been told you would have to go get a Bonded Title from California and it is a pain.....For $700 for this Big Block w/ A/c super long bed it might be worth it...it even runs!
