Enables installation of a late model viscous R200 shortnose (Q45 or Z32), or Z32 R230, or the Nissan Armada R230 (2.94 ratio etc!) into your 1970-1978 Z car! Enjoy full control running 10’s or quicker in a modified Z!.

Includes :

• 1) Custom mustache bar specific to Q45 R200, Z32 R230 or Armada R230 (or others as you inform us and we expand the options) Rear mustache bar, custom polyurethane bushing with steel insert sleeve, fully captured. Eliminates factory design that allows side to side 'walking' movement. Single pair of mounting holes allows for one known functional mounting height (some tweaks required depending on rear chosen for install, we’ll have tips on this). Mustache bar will be unique to each chosen differential (ie. Not multi hole mounting as is shown on image of prototype set). Mustache bar design easily allows customer to drill a mounting hole set at a unique height different from our own to accommodate their unique installation.
• 2) Rear cross brace support (allows full freedom to modify factory cross piece to clear finned differential covers etc). This item may even be of interest to oldschool R200 users, greatly increases stiffness of rear mounting setup.
• 3) Custom front differential mount specific to your differential type. Includes spacers to adjust to your desired front differential nose mounting height.

Features:

• Optimized design allows great strength gains in the mounting system
• Fully bushed for proper mounting to avoid stress risers and minimize noise and harmonics
• Rear brace allows user to fully modify their factory brace if required
• maintains excellent exhaust clearance
• our usual top quality design and machining results
• new hardware and height adjustment spacers included

Benefits

• modern technology and performance, longevity of well engineered and powdercoated pieces with premium parts = unrivalled peace of mind
• allows swap to the stouter viscous LSD late model differentials with many gear ratios to choose from
• complete installation when combined with our billet R230 flanges and custom male male axles that have been well proven for years on 10 second Zs!
• stiffened rear mounting helps you retain full control of your Z with motions restrained underneath and power directed thru to the wheels
• no need to spend hours trying to create your own solution that our customers agonized thru in previous years (their requests pushed us to make this available) The few that stated their time investment on do it yourself solutions noted 50+ hrs into their creation of their own diff mounting setup!
• allows full retention of your present Z brake and suspension systems, factory, our own or custom etc
• we recommend combined use with our adjustable rear control arms to allow optimal rear suspension setup
