L, Z, KA and SR all use the same crossmember mount points. You can use the stock B110 L-series crossmember or an A-series crossmember modified.

Or, use the unmodified A-series crossmember with custom engine-side brackets.

Custom Crossmember

You can modify the 1200 crossmember: Have the mounts trimmed to an angle simular to that of a 200B, then cut the 200B mounts in 1/2 to finish the job and locate the motor lower and improve the mounting angles. A 910 Bluebird L20B sump fits almost perfect, reshape it with a hammer a little just so it will clear the 1200 crossmember, maybe 1/2cm.

If using other sumps, you may need to do the following:

• Remove notch from Datsun 1200 xmember
• Reshape sump to clear the drag link

NOTE: These do not fit a 1200:

• Stanza/510 A10 crossmember
• 120Y B210 crossmember
• 510 crossmember

Motor Mount Isolators

The engine mount Brackets and rubber Isolators you use depends on which crossmember you use.
