1988-1998 GM truck LT fitment notes

LTX17 is listed for 1988-1998 Chevy and GMC C1500, 1992-1999 Tahoe 2WD and 1991-1999 Yukon 2WD.
BRP says a T56, 4L60E, 4L80E or 6L90E goes in without cutting the transmission tunnel.
The kit holds the factory drivetrain angle to head off driveline vibration.
The Sure-Fit crossmember is for 2WD trucks only and comes with its own transmission mount and hardware.
The 340 LPH Aeromotive pump kit mounts the pump on your existing sending unit and includes fittings for the BRP fuel line kit. Its listing names 1998 full size GM trucks.
Radiator sizes: the 28.25 inch core is listed for 1988-1995 C1500, K1500, Tahoe, Suburban and Yukon; the 34 inch core for 1988-1993 C1500, K1500 and Suburban.
Every radiator comes bare or black epoxy coated, for automatic or manual transmission, with or without fans.
For a CTS-V 6L90E, 8L90E or 10L90E tailshaft, a mount adapter bolts it to a traditional transmission mount on the crossmember.

Fitment comes from the product listings. No install guide for the 1988-1998 GM truck LT kit is posted, so these notes are not guide-backed.
