The later ford housings and most aftermarket housings are wider webbed which will require reshaping of the upper control arm brackets to get them in the right place.

So a moser bare housing would have too large of a pumpkin? They make one called a round back retro style housing. Would that be more like what I wanted? Tubes are 3"

Sorry I forgot you have a 74 with the side filler.
It is a better option for 71 to 73 cars.
Most 40+ year old tanks are rusty inside and out, but are not reproduced.
The narrowed Camaro tank adds capacity and mounts in the center for more exhaust and tire clearance when mini tubbing.
the 69 Tank filler neck ends up behind the license plate like the original Vega tank (71-73)
454spyder narrowed his original tank you may also mod the floor and move the whole tank over a few inches.

Narrow the gas tank 3"! Everything moves 3" inward.

Here is how I did it. You must cut in the same place I did to preserve the tanks mounting the same way and fitting properly.

While I was at it, I sumped it and then did the Creem treatment to the inside. Bought the Creem kit from JC Whitney. Worked like a charm.

Here are 2 pics of the Autoweld rear end, look at the upper control arm mounts they are on the incline area of the large web aftermarket housing. Their brackets and alignment fixture only work with that specific housing.
This is why they will not sell you their brackets or use your Ford housing.

12 bolt rear: look how close the upper brackets are to the center section, this is what Monzamouse's brackets are made to fit the straight 3" tube.

In those pics of the Autoweld housing, I notice that the upper control arm brackets are almost centered on the housing; with the 9" having the pinion offset so far, won't this make the driveshaft really crooked in the tunnel? When I built the housing for my drag car, in order to have the driveshaft straight in line with the transmission, I had to weld the 4-link and shock brackets on 2" offset to the right.

Maybe 1100kaw2 will chime in, If IRRC it has a 1" offset. Here are the installed pics of his Autoweld 9 inch. It is not completely centered but there are no clearance issues.

Looking at the tank I may have to relocate in an inch or two, but overall looks like it will clear. I will modify as needed. As for the housing, I plan on keeping mounts in the stock location and narrowing just the outer mount to narrow it up to fit a heim. I will raise the upper mount a couple inches and add multiple holes for adjustment.

I narrowed the rearend 2" myself. Bought a jig to do it and found out the axle tubes were bent 1/4" on one side, 3/8" on the other. In the process of narrowing, I was able to straighten them and get the rear perfectly straight. I left the suspension mounts in the stock location, but narrowed the lowers to get the room to narrow the rear. The spring mounts were moved in 2" per side. I had to send the axles out to have them shortened and resplined to fit the new narrowed housing.

Housings on Ebay here http://www.ebay.com/itm/ford-9-inch-tex ... 1G&vxp=mtr
Here is the Monza link for mini tubbing with a Camaro torque arm.http://forums.h-body.org/viewtopic.php?f=1&t=23454 On my Vega I removed the factory control arm mounts and went with a rear cross member up against the rear foot well and located lower front mounts on that(Chevelle length).He added 3" of with on each side and welded the added space together.On the wheel and rear end widths all depends on the wheel off set used which should be decided on first.With car at ride ht front and rear with no rear housing in it,place wheel/tires in wheel well on blocks exactly where you need them to be and run a tape measure from wheel mounting pad to pad.This is the total rear end width with brakes.Then might as well find engine/trans center line and line up with pinion and calculate the housing from there.

Now I see the offset on that aftermarket setup; 1" on the housing and 1" at the pinion works out the same. The 2" all at the housing on mine looks odd from the back, but with the tube chassis' driveshaft loops, it's necessary to have the pinion centered in the car. I started with an ancient 1959 "round-back" housing and added 3"x 1/4" DOM tubing axle tubes and a back brace. I had another 60's pickup truck housing, but the larger, tapered center section would have created issues with the 4-link brackets.
Interesting to see both housings together and compare the widths-

Im thinking along the lines of buying a moser complete minus brackets narrowed to 50". The 1" offset of the pinion doesnt concern me too much. Wheel offset isnt too much of a concern either as I will be ordering new wheels either way and can order them as needed. Since my car came linked, I'd like to stay with the 4 link over the 3.

Even the deep tunnel of the Vega likes the pinion centered,that raises problems with centering the engine and trans in the steering shaft area.Ideally the eng/trans/pinion should be perf lined up and only drive shaft angle up and down.I don't know where the motor mount/header swap kits put the engine/trans in the front of the car if it is off set to pass side and how much but the pinion center line may have to be taken off of that. A new rear can always be built for a few more $$ http://www.texracing.com/rear_page.html

I too asked them the same question, said no to me too. I went with moser as well. Monzamouse sells four link brackets that are very nice that I used.

Here's a pic of my setup. Moser fan 9" with Monzamouse brackets.

Go with a fabricated, it's not much more and you'll never wish you would have gone to a fabricated. The can measures 15 1/4 so there's plenty of room to move in 2". It's a little tight with the uppers, the nut has to go to the inside but it works perfect. Also with the fabricated housing they cab offset the pinion any way you would like.

Thats a nice set up. What was your width? Also, how much pinion offset did you have? Any pics of what you did as far as the mounts on the body? Sold my rv today and went to order moser rear, but summit said I would need to wait until monday. So everyone has until monday to help with ideas on what to do. Lol
