Hi
I have just received a new roll bar from trl-fabs through e-bay. Apart from having to wait 2 and a half months for delivery, the unit looks good, however the fitting instructions are awful. My question is this, has anyone fitted a roll bar made by this chap, as looking at the bible the boss that he is on about was only on the Chim post 1996, mine is a 1995. He made no mention about years to fit, and neither did he supply any fitting bolts. Need new ones as they will need to be longer.

Any help would be appreciated.

At the risk of being heretical... My 93 chassis had all the mounting points (parcel shelf and outrigger - just needed holes through the tub)

It's not simple but anyone with a little mechanical know-how you should be able to do it.

My advice regarding the parcel shelf holes is to pull the carpet back and drill a pilot hole where the instructions tell you to then shine a torch from the top whilst getting underneath to work out where you need to be. With mine the instructions were about 20mm too far back. That said you need big holes cutting for the rear braces to fit through so the odd pilot hole isn't going to be an issue. Dremel was a useful tool for making these holes.

I also changed the rear fitting method to make things a little easier. I was having a frustrating time trying to align the sockets onto the mounts because it's a unsighted task, you have to feel your way. I fitted lengths of screwed bar into the upper mounting points and secured the rear braces with nuts and washers, that made the alignment job much easier.

If its the same man (Tim Lane - same initial so i guess so) he advertises on here and I've just ordered 2 for each Griff - same spec as jeffsy's. I'll be getting Neil Garner to fit them as he's done a good few now.
There a re different specs so be carefuel - I'vve gone for the top spec which is a little more but provides much more cross bracing so I think well worth it.

The extra bracing works in the Griff but gets in the way in the Chimaera. The cubby-holes behind the Chimaera seats have covers that would be trapped by the cross bracing

Hi

Just having a bit of a nightmare fitting the roll bar, firstly the driver side bolt was rusted in so that sheared off. Had to grind the welded bolt off.
Then having found the two welded boss under the parcel shelf, the threads were corroded as once I put the bolts in to hold the bar in place to drill the two holes to locate the bottom anchor point, the bolts now go straight through.
All the bolts seem to be M10's, so can anyone tell me what the next size up should be so that I can get some bigger bolts and a tap so that I can cut the new threads.

Are you seriously asking what is the next size up from M10, or is this some sort of trick question?

The top threaded bosses are 7/16 UNF. You need to borrow a tap to clean the thread before trying to fit the bolts. Your local garage will have the right size tap, it's a common thread for seat belt mounts. The bottom fixings should be nuts and bolts. Just remove the original and fit anything of similar diameter.

You can get metric with fine pitch at a push, just not very common.

Thanks guys I am going for the 7/16th option as my mate has a tap that size. I did know that the next up from an M10 was an M12, just wanted the imperial equil which is the 7/16th.

I stuck some copies of an imp-met converter on t'internet that I wrote for myself and keep sheets of in the garage. It was perl generated just using 25.4 in 1/64th increments.. Might help someone.

Hi FlipFlopGriif,
Neil garner is fitting mine on Tuesday (21st), when are you there ?
ps, Tim Lane seems a nice bloke,would have thought quite approachable for the guy fitting himself.

Roy.
