Updating the Hardtop Rear Catches


This page covers the replacement of both rear catches with the modified catch, Part Number: DXW 10020OPMA.


The original rear hardtop catches simply hooked under the body fixing hooks, which meant that the hood was able to flex downwards or be adjusted further down thus over-compressing the seals, resulting in squeaks and rattles, marking the body and causing wear on the softtop hood fabric.

The new modified catch has an integral height stop shoe 'A', which controls the hardtop height. When adjusted correctly, the height shoe registers on top of the existing body fixing hook. The catch is then clamped to the hook lower as with the original catch. As a result the hardtop will compress the rear seal a predetermined amount. This eliminates excessive seal compression, which can result in the hardtop fouling the tonneau deck.

This modification took place in late 1997 and effects all standard hardtops up to 'Hardtop Serial Number' F493. This number can be found hand written on the base of the hardtop B-post. (The preceding letter to the serial number is consecutive, i.e. E....being an earlier build than an F...., the number is consecutive only within the letter range).

It is worth noting that the seal that is fitted along the rear edge of the hardtop was also changed from a foam seal to a 'D' shaped rubber seal. This modification was from VIN 014487 onwards.




PREPARATION:

Remove the hardtop from vehicle and place upside down on a soft-covered work surface.
Take care when handling to prevent scratches etc.

FITTING PROCEDURE:
  1. To remove the old catch, first drill out securing rivets 'B' with a 5 mm drill.

    IMPORTANT:Use either a short reach drill or a spacer block to prevent penetration of the outer hardtop skin on breaking through. A simple spacer block can be made out of a small piece of wood. Drill through the wood and then, leaving and holding the wood on the drill bit, drill out the rivets.

  2. Remove the loose rivet heads by tilting and shaking the hardtop until they can be retrieved from the gaps in the lower 'B' post. Ensure all four are removed to prevent rattles.

  3. Fit the modified catches with special securing rivets, Part Number DYQ 100340.

    Ensure the riveter hand tool used has a nose narrow enough to enter the catch carrier. Failure to ensure this will result in incorrect register of the rivet head.

    You may find that more than one compression or stroke of the riveter is required before the rivet itself is fully fixed and the pin shears. Be aware that the pin may be loose in the rivet after the initial compression of your riveting tool, and if you are not careful when you reload the riveter, the pin could be pushed fully inside the rivet, leaving you unable to retrieve it.

  4. Re-position the hardtop to the vehicle.

  5. Re-clamp the header catches to ensure the hardtop is pulled fully forward.

  6. Adjust the catch clamps 'C' in the same way as previous catches until secure.

  7. Check that there is adequate clearance between the hardtop rear rim and the tonneau deck.

    NOTE: The rear catch height adjusters are pre-set and should not require further adjustment. However if sufficient clearance exists, the adjuster foot may be screwed up or down with an open ended spanner until acceptable.
