stripping
 

just started stripping my sierra what parts shall i keep and what bits are sellable

All depends on what engine you are going to use but the basics are:

• Engine
• Gearbox
• Uprights, brakes, rear drum/discs
• Brake Master Cylinder
• Handbrake
• Propshaft
• Diff and shafts
• Steering Column and wheel
• Battery
• Wiring Loom

Pretty much everything on page 28 of the book.

As for selling, if you are going the bec route then engine and gearbox. Other than that it really depends on your sierra spec as the giahs trim, seats ect are worth a few quid.
