Hey guys, I have a chance to get any parts off a 2001 Blazer 2 door automatic, what should I get that usually costs a lot to buy new?

so far I’m thinking alternator, starter, grille, headlights, taillights, dash bezel, anything else?? TIA

 

I think you have started a good list.

LOL - depends more on the space available to store...
...all of it!?

I kept from my 1st gen:
- rear hatch
- all the lights
- wiper/turn/ switch assy
- ignition switch assy
- bumpers
- grille
- engine complete
- transmission complete
- radiator and expansion tank
- wiper motor
- complete wiring harness to the engine including firewall pass-through and connectors
- ECU
- instrument cluster
- ABS module
- A/C complete assy
- seats and rear bench

What I should have kept as well:
- brake calipers
- rear axle
- steering wheel

Actually I would cross-check with auto-parts stores catalogs to figure which parts you cannot come by, or are expensive. This will limit the number of parts you should really keep. Also have a look a the parts which are sold very often. May make a $ or two.
