ok so a 4 speed is easy to swap. and im talking about a 3 speed manual not auto. so how much would it cost to get a used 5 speed and switch it to a 5 speed? can i buy a used 5 speed from say a less popular mustang like a late 70's early 80's, so its cheaper? please put this into dollars because i dont know exactly what all the terms are, i appreciate it. btw i will be doing this myself with help from a mechanic, so dont add in mechanic fees. would it be reasonable (as in price) for me to buy a 3 speed manual 1967 coupe for say $4000 and put in a 5 speed?
thanks

Well you would need the bellhousing adaptor plate, clutch, clutch cables etc... not sure if you need pedals or not. Look it up at www.mustangsplus.com

looking at all the costs, im leaning towards just a 4 speed. it seems a lot cheaper. is there a huge difference between the 4 speed a 5 speed, with gas mileage, performance ect? if i was to swap a 3 speed out for a 4 speed, would it be better to get 5 speed, it seems out of my price range.
thanks

The 5 speed has an extra gear, so it will allow you to run a lower gear ratio, and still be able to drive the car on the freeway.

You`d be happier with a 5 speed. Just make sure and do your homework, learn to read the tags. There are some T5`s that are desireable and some that are not.
If you get one with a T5 bell housing I don`t think you need the adaptor plate.
But then you might need to switch to cable or hydraulic clutch actuator.
None of this is rocket science if you do a little research ::

If you use a spacer plate then your stock 3speed clutch linkage will all work...I made my own spacer plate out of 3/4" thick 6061 $1.50/lb on the surplus market. I'm using a Tremec though which has the same bolt pattern as a toploader. The next thing to consider is driveshaft modifications for correct length. There was, and I assume still is, a wealth of information on the web regarding these swaps. I would say a low buck T5 install should run around $600 with a good T5 donor in the three or for hundred dollar range.

Well the two in the paper (Recycler) right now are a little steep at ~$400 asking. But, I only searched for "T5" expanding the search with additional keywords would produce better results...So, Recycler, Ebay, word of mouth, that's what I would try until I found a post '89 trans within 100 miles from El Cajon and under $300.
