  • Goodbye, bonnet and boot prop-rods! (Not for purists!)

    Having to walk around the car to disengage the prop-rod on the bonnet has always been a minor irritation. So when I heard that Clark & Clark Speciality Products (best known for Spitfire parts, but also purveyors of the upgraded TR6 central console, and those clever cup-holders that clip onto the gear shifter surround) had come up with gas-strut kits for the TR6 (both bonnet and boot), I had to give them a try.

    I fitted the kits last weekend, and very pleased with the result. Now the bonnet raises with a fingertip, and it can be lowered easily from the driver's side. Hallelujah! In addition, it does permit about 10 extra degrees of tilt for the bonnet too.

    The gas struts bolt to clever adaptors that fit into the bonnet lateral support, using the existing bolt hole. The adaptors are nicely made and very stout.

    The only hesitation for me is that you do have to drill through the inner wing to fit the ball stud for the rear end of the strut, which is secured in the wheelarch with a washer and Nyloc nut. It drills through a double-thickness of sheet metal, so is plenty strong. I cut some washers from thin gasket material to sit between the ball studs and the metal of the inner wing.

    Here is the other side:

    I also did the boot. The struts easily lift the bootlid, complete with luggage rack.

    The driver's side of the boot kit uses the mounting locations for the stock prop-rod. You do need to fit a couple of brackets on the passenger's side, again requiring drilling.

    So - not for everyone, I realize, but my car is very much a resto-mod these days, so while I do dislike drilling, I'm pleased with the outcome.

    (I will also say that Robert Clark was great to work with on this - I believe I am one of the first to install these kits on a TR6, so was somewhat of a guinea pig.)

      That's very slick and long overdue..... did you have any fitting problems or is it straight forward?

            What I was looking for so many years.....But looking at your pictures, they should have thought about bolting an adapter to a front wing nut on each side.....not that far.....instead of drilling a hole!

              Funny you should say that...I had the same thought.* I sent a concept to Robert Clark of such a bracket...he is considering it.* I may prototype test it for him.* If it works, he may add it as an option to the kit.**

              (If successful, I'll have the holes filled it when the car goes for paint.)

              Shorter strut or longer....? For the trunk, it' another thing.....Don't see an option..You do?

            I love it! If that were available when I had my car, Ashford would have thanked me for that conversion! I am a fan of "proper" modern conveniences that really don't detract from the original. Had this been available in those days, we would not have the crazy mechanical boot slide latch or the cheap prop rod.

                Thanks. Yes, they do fill up the engine bay quite nicely.

              Very straightforward, no real issues. Robert Clark provides very clear instructions.

              I did have to slighly flex outwards the lip around the boot on which the seal fits outward on the driver's side, so strut cleared it when closing, But that was it.

              Took about 90 mins to do both boot and bonnet.

                Man Keith, that's slick. Gotta get me a set. Then I can finally paint that area on the wheel hump where the prop rods been scraping the last 46 years!

                  Same length strut. I came up with a bracket that attaches at two points - the wing fasteners in front of and behind the head of the strut. So, the head of the strut remains in the same position as it does in my pictures.

                  For the boot, I have not considered an alternative. Though, I found that one single gas strut was capable of raising and hold the boot (with luggage rack). I like the second strut (on passenger side) though as is prevents the bootlid from its natural tendency to twist.

                    Keith, can you post some pictures of your front brackets? Your comment is very interesting for the back lid, having only one strut......

                  Very slick, Keith. I'm going to bookmark this for the 250 project. Looking forward to studying your webers at the Mitty.

                  Hiya Kevin,

                  I’ve got them coming for my 250 project. I’ll try and figure out what mods need to be done to get them to work on the 250. I’m more concerned with the boot ones fitting as the structure of the TR6/250 lid is quite different.

                  Cheers

                    I have sent an e-mail to Robert Clark and he is looking for the feasibility of a bracket not involving new holes in the tub, for a not too high price increase.....

                        Very nice. I was more thinking about using only one bolt....using two tabs, one in front of the bolt, one after, to make the bracket stable....I'll try to draw something...
