Rust repair cost on sills, floors, and bulkhead decides whether a project is a car or a money pit. Panel availability and weld quality matter as much as the quote.

Panels and welding
Reproduction and used panels exist with varying quality. Demand continuous weld quality and rust-inhibiting prep — not spotty cosmetic patchwork.
Costs and when to walk
Get itemized estimates. When metal work exceeds the car’s honest finished value by a wide margin, walking is a skill. Bulkhead horror stories end deals for good reasons.
Common mistakes
Skipping cold and hot tests, trusting verbal history without invoices, replacing parts before measuring, and ignoring rust while chasing mechanical gremlins. Photos from another market or year are not a parts catalog.
When to stop DIY
Stop when you lack the gauge, puller, or safe support the job needs — or when the first repair did not change the symptom. Pay for diagnosis with someone who sees R107s regularly.
Practical takeaway
Pay for a lift inspection before you fall in love with paint.
Shop notes and paperwork
Keep invoices, pressure readings, part numbers, and dated photos of the area before and after work. The next owner — or future you — will ask what was actually done. Verbal “we took care of it” evaporates at sale time.
Safety and scope
Use jack stands on solid ground, relieve fuel/coolant pressure before opening systems, and disconnect the battery when the procedure calls for it. If a step needs a specialty tool you do not own, rent it or hire it — improvising with the wrong lever is how fasteners and fingers break.
Verify against the factory manual for your engine and chassis. No invented personal car details here — use your plates, invoices, and measured symptoms.

Safety and scope
If this topic intersects fuel, rust, or safety systems, fix the safety and leak paths before cosmetic or convenience items. That order saves money twice.
