NTC7370 (twin tube construction) suits Defender up to 1994 (up to VIN: KA930455) and Range Rover classic up to and including Oct. 1985
NTC6860 (triple tube construction: stiffer bush) suits Defender from VIN: KA onwards (approx 1993 onwards), Range Rover classic 1986-94 (less anti-roll bar, less air suspension) and all Discovery 1
NTC6781 (twin tube construction: softer bush) suits Defender from VIN: LA onwards (approx 1994 onwards to current model), Range Rover classic 1986-94 (with anti-roll bar or with air suspension) and all Discovery 1
Both these bushes (NTC6860 and NTC6781) are interchangeable, we don't know what the advantages are between one type and the other apart from the price differences.
PLEASE NOTE: The aftermarket bushes are low quality, you'll be lucky to get 6 months out of a set, as a result, they are sold without warranty.
