Coil balance inquiry

My existing 1/2" Coil Single Support was a style that had a spindle on it. Then the spindle would go on the axle that axle is what gets fastened to the frame. I'm unable to force the spindle into the new coil balance. It was very difficult to remove it from the old broken coil balance. Is there a risk to not using the spindle? Should I purchase what you offer for the 1/2" Coil Single Support. Is it easy to get the new coil balance (that I recently purchased from you I purchased the 5.5lb coil balances S160-05) onto the 1/2" Coil Single Support? 

Is it easy to fit a 5.5lb coil balance onto the 1/2" Coil Support?  If so,  I will order it.   I've already be able to install the new PIvot Shoe's 15-199 but I'm using my existing coil supports.  I'm thinking it may be better to go with the new coil supports otherwise in the future my existing coil support will probably fail since I'm not using the spindle.   

What are your thoughts on this: 

Is it easy to fit the 5.5lb coil balance (item#S160-05) onto the 1/2" Coil Support (item#15-150S)?   If it is I'll probably just order 4 of those and install them.  

I've been able to get everything back together and the windows are operational.

I'm thinking for durability sake I'll probably just purchase 4 of those supports from your company.  I should be able to make it work with those.   I've learned about my windows over the last week!  

The axel of the old support had what I'm calling a spindle on it.   

My current installation just has the axel holding the coil balance which probably isn't the best configuration.  

Here are a couple of pictures of what I was referring to: 

Hi Tom, 

Thank you for getting back to me.  I just tried to install the new supports yesterday and they were impossible to get inside of the coils.   Might be because I have been using the coils with the old supports without the drums in place just an axle and maybe that has caused the inner diameter to become smaller making it impossible to fit the support inside.   I worked on just one window last night and tried to trim a little bit of material off the support but when I installed it the window was not working correctly.   The support is too long by about a 1/4" so I can't get the window to latch in properly.  The coil is so tight it's not working correctly.  So I just removed the new support and went back to the old.  For now the window is 100% better than it was when I started so I'm just going to live with my current setup.  If the coils should break prematurely I'll just by new and consult with you guys with more pictures when that time comes.  Right now the windows go up and down with just a little effort which is fine.  

Thanks again, 

Michael
