Attach the forward ends of the 'A' frame to

the mounting provided on the chassis,

refer to Fig 131, using bolts (fastener pack

30R011A Item 1), passed inboard, with

large diameter plain washers (14), you

need to space the A frame with the

washers, there will be 4 one side and 3 on

the other side between the A frame and

the chassis, then put 1 washer (14) on the

other side and then put on the nyloc nuts

(7). Do not tighten the 'A' frame fixings.

Check that the De Dion tube is centralised

in the chassis. Measure the gaps

between the De Dion tube end plates and

the outer edge of the chassis tube; these

should be identical 2 mm. If adjustment

is required move one of the washers (14)

between the chassis and 'A' frame until

the required position is achieved. You will

normally have 3 washers one side and 4

the other.

driveshaft with a soft faced hammer.

Ensure that the driveshaft is held as

straight as possible to prevent damage to

the boot.
