Roof Rack Write up on Hard Top
This is the first step I did. I will have the remaining parts of the thule rack this week and add more pics with the Rack Basket itself.
Once again Please note – This is what I did- You follow my steps and mess up, its on you- buy a lot of silicone and fiberglass.
Parts
Thule TB60 rails
2 – 10-24 x2.5 screws
2- 10-24 nylon lock nuts
Thule TK1
Thule 430
Thule 58" bars
Total cost around $350
Regular size drill bits 3” 1/8 and 7/32 – the bits they give are to short
First I took the rails apart and lined them together against the last hard top hump. I placed the metal rail against the hardtop and bottom rail I lined up and Blue taped. Measured twice and tape then Drill.


First I used the 1/8th bit as a pilot for all 12 holes then the 7/32 for the main hole. Let the bit do the work, don’t push down to hard, otherwise the fiberglass inside will break spread.
Remember, where I have the rail placed. I went through the strongest part of the top that’s 2x reinforced, so when I drilled through the top I kept it going through the 2nd support beam.
Now I used the provided silicone and silicone the hole putting more towards the outer edge.


Then put the 10x24 screw in the front b/c that part of the top is thicker. And one screw in the rear to keep it lined up.

Then finished putting in all the other screws with washer and nuts.

Final look:



From inside the back rear, I think I’m going to fabricate a support bar (this last picture) going from the last screw to the bottom ledge behind the roll bar going straight down.
Take the TK1 Bracket and Bar line it up




Place the basket on the bar and square it all up

Tighten everything down


Bolt up the basket and Im done

Finished- Drove around- went highway speeds 80mph no noise. Going to add the front deflector for little gas savings. Rack is strong and will be doing tests to see how much the racl can handle.

Great write-up!
questions:
The doubled wall feels strong. Is it hollow in-between?
Is there a need for expanding foam, etc???
I'm wanting to run my "clam shell" for luggage, when taking the dogs on trips. My only concern is the wind lifting the topper, and stressing the bolted holes.
The rail with multiple bolt holes seems a better answer, than rails with just two feet/contact points.
Thanks for documenting your projects. This is a great site, and you add alot to it...

It is hollow in between and although I dont think its nessasary, I would recommend it. To do this, extra holes have to be drilled in the inside rail and filled.
With the Lift issue, I ordered the Thule 873 $55 wind deflector for the front of the basket that will keep the basket from lifting and have less drag.
DBB888, I always look forward to your write-ups! Great job and well documented as always.
I'm just waiting for you to create some sort of door stops using small gas shocks similar to that of the tailgate shock mod (hint hint)
Door stop huh?!? Interesting- give me a few weekends on this.
As far as taking the top on and off, it adds about 22-25lbs. no to bad. I have the heavy duty suction cup handles and a few nephews and cousins always around to help me.
I might make a rig that I back up into and hoist it off. Just a thought- maybe next summer on that.
Let me think about this door shock stop thingy... I'll be in Vegas this weekend for a bachelor party 4 days 3 nites
:toung:
CRAZY WEEKEND-
Wife not to happy but what to do
