So my new to me K75s 1987 came with a Westco battery that when you place the bar over the battery and run the long bolts 176mm btw , the theads don't even engage with the base without twisting the bar bending/distorting it to grab a thread or two.
The battery appears to be slightly taller than the OEM unit. Anybody else experience this? Whats the fix?
Ever try to buy a 180mm x 6mm x 1.0mm bolt?
I tried adding a coupler at the base with threaded rod in the base...only the 10mm of thread I ran above the plate into the coupler makes the top of the bolt hit the ecm brick above the battery. tight clearance....
This just feels stupid, but if I could BELT SAND 1/8" of plastic off the base of the battery :mbird the original bolts would work...How much meat is there on the bottom of that casting. stupi\de.
Or, I thought about somehow building a recess into the bar that would bottom out the bar a few MM lower. Id have to weld a thimble shaped socket to the bar, below the hole. complicated fab....
I could divot the bar with a punch, cold stress or may heat with a torch and beat on the hole area to drive the top of the bolt lower by a few MM..
ideas? help!

so dimple the bar to have a lower location for the hole..I can certainly heat it red, blacksmith style divot the metal and repaint...only need a few mm. Jonny. thanks.

If you want to go the route of buying a longer bolt you can get them at mcmaster.com for a littler under $7 each.

When the bar is on the battery are the flanges of it resting on the battery or is the longitudinal center of it?

I have the same problem with my "Big Crank" ETX-30L battery from batterymart.com. Haven't done anything about it yet, but plan to get either longer bolts, or nuts and all-thread. Going to need a fatter rubber grommet to retain the coolant reservoir as well.

When I bought my Wesco battery from Beemer Boneyard they included the longer bolts - or I ordered them from there, I forget. I made a longer grommet to hold the coolant reservoir using a cut-off section of a rubber leaf spring bushing that I found in my 'leftovers' supply bins.

Bolt Depot has 'em http://www.boltdepot.com (http://www.boltdepot.com) , so does McMaster-Carr https://www.mcmaster.com (https://www.mcmaster.com/#=16ucqn7)

Greetings Brick bretheren.
Laitch, best I can tell, I have the bar oriented with the battery touching the longitudinal in the upright orientation. :clap:
So today I patronized my local specialty hardware vendor Fastenal and while they didn't have the length I require they did have lengths of threaded rod, so reluctantly and knowing the weather is balmy I opted for the scheppo fix...threaded rod and doubled nuts.
Then to my rescue was Brick newb Robp and his online vendors suggestions. I had prowled mcmaster a month back and they didn't have it in stock however this boltdepot.com looks to be the solution I required thanks for the tip. The rod will get returned...:
