i need a 48 or a 49 in driveshaft
and i cant find any cars to get one out and the only why to get one is to have it custom made so does any one know what car i can get the right size driveshaft out of.

thanks and please help its frustrating!

What kind of car it is and it's tranny type would be more helpful.

tranny = c6

car it is in = ford fairmont futura

driveshaft i need is a 48 or 49

it is a 1983 fairmont has a v8, c6 tranny and stock 7.5 rear end

the only thing that is holing me back from the road is the driveshaft and shifter but i want the driveshaft first.

Call some junk yards and see if they have any. If you can tell me how many input and output splines you need that would make it a lot easier to find one. Once comes to worse you'd have to buy a driveshaft that fits the input/output splines and have a machine shop cut and weld it to size.

well i already have the yoke just a driveshaft i need. and i think it is a 31 spline i think thats what it is.

all i need a 49 inch driveshaft. i have longer ones if you want to size it for me but all i need is to find out what car or truck i can get a 49 inch driveshaft out.

Well not sure on that one as my knowledge is limited to Mustangs, Camaros, and Corvettes, but I do know that if you can get a longer driveshaft with the same input/output then you can have it cut and welded to the size you need.

well a ford fairmont is based off a fox body mustang here ill show some pics as well

and i got a long driveshaft i need someone to cut

but i got a big fear of that! i got a big motor that puts out around 300 to 350 hp and if it might break the weld from the hp and tq it puts out. because i do some hard shifting sometimes and beat on my cars like my stang and my truck i beat on them and do hard shifting and i want the driveshaft to stay in place instead of breaking in two at the welds.

If it's properly welded, it will never break, only a half ass crap weld will break. 300 rwhp 350 rwtq may sound like a lot, but it's really not.

ya. and 300 - 35 its a guess because my uncle said it would put out that and he builds cars and motors for nascar and other places as well.

my car is not build but its bored 60 over, 750 cfm holly ported heads and intake, and hot cam(aftermarket cam)(my dad got it for me for my bday i dont know what brand it is) and some other bolt ons and stuff so around their. also i have a c6 trans

and i might weld the driveshaft
