1971-1976 Impala LT swap fitment notes

LTX3 is listed for the 1971-1976 Impala.
The long tube headers are listed for 1971-1976 Impala and Caprice and are made for LT engines on the Muscle Rods mount kit.
A mid-length LT header for the 1971-1976 B-Body is also offered; its listing has no extra fitment detail.
This page has no complete EFI tank. The Aeromotive Phantom 340 kit puts a 340 LPH pump and baffle into your existing or original style tank.
The Phantom kit includes the pump, hanger, lock ring, baffle with fuel bladder, a drill guide and instructions.
BRP describes these aluminum radiators for 1968-1972 A-Body and 1971-1990 B-Body cars, in bare or black epoxy finish.
The Sure-Fit crossmember is sold by itself for 1971-1976 B-Body Impalas, and the LT mounts with frame brackets are sold separately as well.
Transmission adapters bolt a CTS-V T-56, Camaro TR-6060, MG9 TR-6060, 8L90E, 10L90E or 2009-2014 CTS-V 6L90E to BRP crossmembers.

Fitment comes from the product listings. BRP has not posted a 1971-1976 B-Body LT install guide, so tunnel and transmission fit are not covered here.
