Instaling a SIII Lightweight Handthrottle in a SIIA 2.25 Petrol

Hi,

Recently i bought a hand trottle from a lightweight for my 2A petrol. Its the "cheese wedge" type It came with everything and ive figured out how it works however i need to know where the handle part mounts on the bulkhead (as mine does not have the holes for it).

Theres a small arm 2" in length that goes through a hole in the bulkhead and attaches to the arm on the throttle linkage.

Could someone be very kind and give me some measurments as to where the hole should be in the bulkhead (somewhere on the left hand side of the lower centre portion) so i can put it in.

Thanks )

i allways though lw had hand throttle on dash already a u bolt pull type
