£24.00 inc. VAT

The Jass Performance Frankenstein Bolt Replacement Latch bolts the hardtop securely to the 89-05 Mazda MX-5. Replacing the slip-on mechanism of the Frankenstein bolt, the latch prevents knocking and squeaking that can occur when a hardtop is too loose.

The Rear Latch Replacement is intended to be used in conjunction with fixed hardtop brackets we offer.

They have the following advantages vs. the OEM rear latch:

– allow much easier positioning of the hardtop closer to the front windshield frame (as the Frankenstein bolt prevents this in the OEM configuration)

– provide additional fixing now in both horizontal and vertical directions

– provide vertical fix and by pushing the hardtop slightly down minimises the potential squeaks caused by the lower hardtop seal

The set consists of everything needed to replace the OEM plates.

Warranty information

Warranties cover defects in materials and workmanship only. Warranty is for replacement of a similar product, repair of the original product or refund of the purchase value only and excludes all labour and incurred charges including towing, fitting, inconvenience, and purchases of other manufacturer's products. The warranty is good for the period stated in the additional info tab from the date of purchase. Mileage warranties are for road use only and proof of mileage is required. Products must be installed by an independent experienced professional mechanic and the suspected defect must be present at the outset. The warranty does not cover damage caused by incorrect installation, failure to comply with the maintenance requirements of the vehicle, processing or otherwise changing the product, ordinary wear and tear, or any other external influences. Warranties are invalid if the product is used for racing, rallying, drifting, track days or any other form of motorsport or competition. Please refer to the manufacturer's own warranty documentation for more information.

Making a warranty claim

Proof of purchase receipt showing the date of purchase, proof of mileage at installation, proof of current mileage and invoice of the work undertaken by an independent experienced professional mechanic must be supplied along with the returned products for a warranty claim to be considered. If your vehicle needs to be used whilst your warranty claim is considered replacement parts from the same manufacturer should be purchased through BOFI Racing. In the event of a successful warranty claim, we will refund the card that was originally used to purchase the replacement parts, in full or in part depending on the nature of the claim. BOFI Racing reserves the right to make full or partial compensation at its sole discretion depending on the condition and mileage use of the returned suspect parts. For example, if you have used the part for several thousand miles before a defect is noticed, only partial compensation may be offered.
