i have an 85 f150 with a 351w and AT c6 transmission. i know where i can get a deal on a complete 87 f250 with a 5 speed. i want to put the 5 speed in my 85 and was wondering if there were any tricks or special things i need to know before diving into it. i am concerned about it going from a 250 to 150. but maybe it doesnt matter. the 87 has a 351w also, runs and drives. can anyone help? done this? thanks!

 

A bunch of things.... Need a third pedal, clutch master cylinder, slave cylinder, the trans mounts are different, need a hole in the floor and the drive shafts are different lengths. Not saying its not possible, but its a whole lot easier going from a manual to an auto than an auto to a manual. But I guess if you have the whole truck you can take as many parts as you need.

 

i hear ya, and i did all the work myself to my truck so i got the ability to do all this and make it work im just wondering if there is anyone out there whos done it with this combo of year and make by chance. i know drive shaft ends could be different and small stuff. thanks for the help and ya i can rip all the parts off the 87 and put it onto my 85. my converter i just paid 400 bucks for will be for sale too i guess lol
