For those Z32 owners with cracked/broken t-top handle finishers, this NLA product would normally have to be sourced as used...and hopefully they wouldn't crack again.
ZSPEC has reproduced these for an OEM-fit with OEM-matched colors (Charcoal, Red, Blue, and Tan). Even the script/writing and coloring details were added to make it difficult to distinguish from the originals.
See ZSPEC's site to order a set (discount on a 2nd set if you'd like one on the shelf just in case...) - Tan/Blue/Red are in stock, Charcoal will be available in ~1 week from this posting.
