Not got a reference guide to hand but all of the 3 bolt starters are for 1108 and 956 engine and the lrs prefix is lucas own reference for rebuilt unit and may be different manufacturer and design to on your car
All will fit just some are small enough to be removed easier a pain if you get yours off with manifold on and new one is bigger
I bought a new bolk unit from Mr auto in france for about 30 delivered and been on 2 yrs now
If the photo shows 2 bolt fixing it is for 747 and 845 engines and not suitable at all
