I can`t really answer that 1 fella as i don`t really have the knowledge of them.
I`ve seen pics of full blend before and they do look like mine + PeteG40 on here
saw mine in the flesh and he confirmed this theory.
I think there is probably a few idea`s of full blend depending where it is done.
There seems to be varying quality in degree`s of workmanship.
some are very well finished with nice polishing and others are rough as fuck.
If i were responsable for mine, it would not look like that in my pics as you can
clearly see the Die-Grinder marks wich in parts look like they got carried away
with themselves.
But then, if i had the money spare then i`d have had 1 of those new chargers
recently advertised on here and ebay because then if i decided to do it i could
ensure quality porting.
I suggest that you talk to others on here like pete, hayesay, as they are truly
knowledgable in this department.
