I want to share a set of drawings I received from John S. John sent me the MK10 chassis drawing, Lower A-Arms for Front and Rear Suspension and the Rear Hub casting. Thank You John, for sharing these valuable pieces of information.
PS: Elden spare suspension parts are available from MK Motorsports in the UK: https://www.mk8motorsport.com/
and GMT in the USA: http://www.gmtracing.com/
Note: GMT acquired the jigs for the Elden from Pat Price Engineering.
Note: Just got this from Peter Hampsheir.
The differences between the mk8 are minimal.
After 1981 the weight minimum was increased by 50 Kg to allow for mandatory for extinguisher. The Mk8 was already under weight and so I decided to put the exrta in the chassis for strength. The main members were increased from 1″ sq to 1 1/8″.
SCCA roll bar regs increased to 1 1/2″ dia. Rear radius rod mounts went to clevis mounting and the engine Y frame was made detachable. The rear cross-member was raised to permit inboard brakes.
The original MK 8 chassis drawing was left on train and was superseded by the Mk 10 drawing 10C1 in Jan 74. This was the last mk10 chassis drawing.
