I am not sure what your looking to spend but I found these on ebay. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33731&item=2453533322

There is no 9 inch that is right for a Monte.
The monte needs 60" flange to flange.
Stock 9s come in the following

57-64 ford 57.25"
64-71 full size cars 61"
67-71 mustang 59"
79-81 Lincoln verailes 58.5 come with disc brakes
77-80 granada 58.5
72-79 intermediate 63"
77-86 F-150 65.25"
77-86 E-150 69.25

As for tranny I prefer a manual and saginaw 3 speeds are strong enough and cheap enough.
You will need somewhere around a 6.00 final gear for that size track. You can find 9 gears in that ratio. Or find 3.70 and run a saginaw in second gear.

quick performance in ames ia sells complete rear ends that might even be one or there on ebay jr motor sports also sells housings if you want to buy everything brand new with after market axles for a non floater your look'n at around 6-800 without gear and brakes. this doen't have much to do with the rear end but is that the biggest cam you can run thats kinda tiny considering the good heads and headers your running. gear wise those are probably some pretty big tires would start in the 6.50 range will probably put you in the 5800-6500 range rpm wise

71-73 mustang/cougar 9" rears are the perfect width for a metric car. you can also find this same width rear end in a 70-71 torino/montego/cyclone/ranchero. they are all leaf cars so brackets will need to be fabricated.

jay116, 67-70 mustangs use the same width rear end. 71-73 use a wider 9".

these are housing flange to flange measurements, not including the distance from the housing flange to the axle flange....

65-66 mustang and granadas/monarchs....52.25"
67-70 mustang/cougar....54.25"
71-73 mustang/cougar/torino/montego/cyclone/ranchero....56.25"

you can add about 4.5" to the housing width to get the overall width and you can always use different offset wheels or spacers to get you where you want.

all of these housings are tough to come by but 8" axles will directly interchange with small bearing 9" axles.

if you know how to fabricate, you can buy the brackets and put them on yourself. just gotta do the ol trial and error thing as far as your pinion angle is concerned.

I just copied the data right from the Steve Smith book. I wasn't trying to say you cant use something in stock form. I was trying to say you have to make compromises when using stock gear. Personally I think go wider and use more back space on the rear wheels.
Thats what we do on our Monte. The person that built the car used an f-150 rear and we are going to use 5" backspaced 10" wheels on the rear. The rear clip is 2x3 tubing. So we have plenty of space.
