Good time to check your heater box for any possible repairs or preventative maintenance, probably fine unless you had some issues.
The gauges depend on what works and doesn't. If you have gauges that just need refacing and cosmetic stuff you might tackle that. I had auto instruments refurbish mine, cosmetically and fixed the tic tock tac/clock, made sure all gauges were working, etc. Needed a lot of work but looks, and hopefully functions, like brand new. My dash is still out pending other work needing done. I need to address the emergency brake too but haven't tackled it yet.
You could check your wiper pivots and make sure they move freely, not leaking etc. Mine were frozen up and I had to find some used ones here on the forum, they are not reproduced.
