87 With Roll Deisgn Arms

[PFronz]

I have a 87 with Roll Design front arms. I bought it with the arms already on. I need new tie rods but I don't know if I need +1 or +2. The ones currently on measure app. 13 1/2" end to end (without the swivel ends). Can someone tell me the stock length and then if I just add on? For example: if stock length is 11 1/2" and these are 13 1/2" then do I need +2 tie rods?

I don't think Roll ever made +1, so a +2 should be correct.

 

If still in doubt, call Roll.
