will flaming river 1540 16:1 box fit 1965 cuda?

Hey all,

i've got a 65 S cuda that i built back in the 90's, with a 5.5 lock-to-lock manual box. i'm also running '68-'70 340 exhaust mainfolds, which is already real close to the steering collar bolt head. i've read all the threads re the FR 1540 box, and have seen that some feel it will direct fit pre-'66 a bodies, but can't find a thread where someone actually did it. just called Flaming river, and tech guy said there must be something different with pre-'66 cars, but he didn't know (???). jegs and summit say '66 and up.

has anyone actually direct fitted one to a pre-'66 a body, or know where someone has? if so, i'd appreciate input on how it went, and whether any mods were needed. from what i've read, the only possible glitch is the spline for the pitman arm, but not the arm itself.

thanks for any advice! Brian
