Fidelity Research FR-7 Repair


I have a FR-7 cartridge that got wacked in a move and looks bent. I was looking to send it in for repair. I see Soundsmith and cartridge_retipping-5 on ebay. I was wondering if anyone had any recommendations on this. 

I thought about buying a replacement (FR-7 or FR-7f) on ebay but considering the age of these cartridges thought I might be opening myself up to being in the same position I am now. Figured repair would be cheaper. 

I'm using on an FR-64 tonearm and a Brooks Berdan modded Oracle turntable with a Cotter SUT. In the time this has been down I've tried other cartridges but nothing has the magic of the FR cartridge.  Thanks in advance for any insights.

I don't use any rubber rings and the pictures provided above are from the internet to display a $7 the plastic overhang gauge to the OP.  
So dear chakster, You can sell your Feickert  and buy one plastic
caliper which you can use for all your carts/headshell combinaions.
The only thing you need to separte are your tonearms and headshlls
which you use with them. 
I'm not getting the Feickert because my buddy has a protractor. I'll never use another cartridge again. I don't never know where the Orsonic is at this point. My plan is to install the FR-7 and hope it lasts forever. Well, maybe next year I'll buy an FR-7fz. That way I'll have two FR cartridges in the house. Just in case. 

I'll have to check but I think I have an overhang tool around here. Thanks! I'll look at calipers.
Dear lech, your ''info'' is confusing: ''all the carts which I used with
Orsonic'' clearly suggest more than one cart. Well you  don't
need the  caliper for only one cart (FR-7). Caliper is for ''copy'' of
one good adjusted cart. The eff. lenght (distance pivot -stylus tip)
 can be repeated by other carts. 
I own other cartridges. I will never use these cartridges. They were a stopgap because my Fidelity Research was damaged. They were failures in comparison. It’s like I bought a Yugo to get me to work after I crashed my Bentley. Now that the Bentley is fixed, I will no longer drive the Yugo. So, the Orsonic becomes a relic as well. If I find it, I’ll likely sell it along with the other cartridge. Which will remain nameless. I've never setup my own cartridge before so this will be an interesting learning experience.
