Planning a longhood 911 backdate
A longhood backdate starts with the car you have, not just the look you want. A 1974–1989 G-body or a 964 can be the starting point, but the hood, latch, fenders, bumpers and rear quarters have to be planned together. Expect fitting and fabrication before paint.
Keep the later latch, or use an early hood?
The long/short conversion hood combines an early outer profile with an inner arrangement for the later donor's latch. That is different from the 1965–1973 hood, which uses the early latch arrangement. Similar outer shapes do not make the two installations the same.
The conversion hood still needs the surrounding longhood front bodywork. It is not a backdate by itself.
Match the front fenders and bumper
For the RSR-style front end described here, choose the driver-side RSR/ST fender with a fuel-filler bucket and matching passenger fender. They pair with the 9-inch-profile early RSR front bumper and its separate front opening grille.
If the build has a fuel cell or another nonstandard filler arrangement, the driver fender without a filler bucket is an alternative. It is not an extra fender to buy alongside the standard version. Plan the light buckets, mounting flanges and bumper attachments with the shop doing the work.
Choose a rear-quarter and bumper combination
The 11-inch Turbo/RSR quarter-panel pair and early RSR rear bumper form the rear-body combination used in the conversion kit. The quarters are full replacement panels, not bolt-on arch extensions. Check the exhaust exits and wheel clearance before final fitting.
A nominal flare size describes the bodywork; it does not guarantee clearance for a wheel of the same stated width.
The kit or individual panels?
The 1974–1994 RSR-style conversion kit brings the listed conversion hood, front fenders, rear quarters, front and rear bumpers, front grille and RS-style ducktail together. The separate panel links above help you compare the package or replace a component. They are not extras to buy again if your kit already includes them.
The kit includes a ducktail, not the IROC whale tail shown in some example photos. Windows, doors, mirrors, interior parts and exhaust are separate from the panel package. Confirm the final contents and any parts you plan to retain before ordering.
What changes with a 964 donor?
The included earlier-style ducktail needs hinge adapters for the documented tubular 964 hinge arrangement. Confirm whether the adapters are supplied with your package. The front and rear bodywork still need a coordinated conversion; do not treat the kit as a set of stock 964 replacement panels.
This guide does not describe a complete 993 backdate package. A conversion hood with a documented 993 application does not establish compatibility for every other panel.
Plan the work before the finish
Agree on the donor configuration, body profiles, filler, lights, mounting, exhaust exits and wheel package with your body shop. Test-fit the complete panel set before paint. If you already have a 1969–1973 longhood, compare the early-car RSR-style kit instead.
For broader build decisions, read the RSR-inspired build guide. For a more standard replacement path, browse G-body parts or 964 parts.
