Uses your 1973-1987 C10 spindles (not included). Inner fenders must be trimmed. For the best bump steer, run 18 in. or larger wheels: up to 6 in. backspacing on 18s and up to 7 in. on 20s. The steering shaft is not included. You may need different headers or an oil pan (stock SBC and BBC pans fit), and you may need new power steering hoses. Already running QA1 coilovers? See the 52625 Crossmember Retrofit Kit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEngine mounts included:\u003c\/strong\u003e The QA1 crossmember needs its own engine mounts because stock mounts won't fit, so choose yours from the Engine Mounts menu. The bolt-in kits put the engine in the factory location, so the bellhousing and driveshaft stay put. The SB\/BB Chevy kit (7740-375) is for small and big block Chevy engines, and the LS kit (7740-374) is for LS engines. The DIY weld-on kits (7740-378 for SBC\/BBC, 7740-379 for LS\/LT) let you weld up your own mounts for custom engine placement.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLead time:\u003c\/strong\u003e Built to order by QA1.
