A lot of work just to avoid a smog check every two years. Also isn't the Currier a smaller truck?

If you want to build a Currier into a 4x4, that would be a different/one-off kind of rig, and you wouldn't be turning an '85 Toy into a '75 Ford.

I haven't checked but are you only 3-6yrs(27 or 30 yrs old car) from no more smog checks, or have they reversed the 27yr date again.

More than tread lightly. Leave it like you were never there, nor anyone else.
