Enlighten Me Firebolt dudes

[DeuceWheeler]

For whatever reason, I only think of this when at work.

I haven't had a chance to look at my firebolt since I bought it and with the cold MN winter, I haven't had the desire.
I am collecting parts to build it this spring, I keep forgetting to take measurements when I am at home. :roll:

I want to put either an OG Monark springer or Abraham Linkage on it.

From what I have read, the Abraham Linkage might be too large for the older frames? Is the Firebolt 1'' or 1 1/8''?

What about an OG monark springer from a women's bike, can it be modified to fit?

I have been googling and searching, but not coming up with a ton of definitive answers.
Feel free to tell me to do my on homework, just thought anyone who has had and rebuilt one of these frames might know off hand.
Thanks guys!

It's a 1" headtube and the ladies monark should fit either with spacers, or re-threading the fork.

I too have the problem of owning a firebolt for far too long and not building it up.
