How do you guys install your engine cages? Mounting points and such..

The guy I bought my baja from gave me a basic engine cage but it doesnt have any mounting brackets and such. Just tubular metal. The top 2 pipes have holes drilled in them, but the bottom 2 dont. Do I have to fab up brackets or is there somewhere I can just bolt it to? Thanks!

The bottom tubes mount to the big transaxle mounting bolts. The top two either mount to the firewall or upper shock mount. You can tell by the spacing. Just hold it up to the car and you'll see what I mean.

You can get the brackets to mount them at Chirco or any other VW store. I believe they're about $15.

I bought my brackets from Chirco but I can't find them on their web site now. I think they were around $20

Yeah, i just found them. They're like $16. Do you guys prefer the shock mount or firewall mount?

You need to figure out what kind of cage you have based on the spacing of the upper tubes. That determines cage or firewall mount.

That's what I was thinking right as I posted the previous post. Im guessing it's going to be shock mount for how wide it is..

Was also wondering about the shock mounts.. The shock tower bolts are angled in and not perpendicular to the car. Do you have to bend the top 2 mounting brackets to bolt them on?

The metal on the cage mounts is light and will readily bend to match the angle of the shock mount bolts. I ran out of threads on mine (replaced rear shocks at the same time) and had to go to a bolt an inch longer for the upper shock mount.

2 of the mounts in a kit should be angled to match the shock mounts. there should be a 5/16 or 3/8 bolt through those holes and through matching holes in the brackets (you'll have to drill 'em) to hold the bumper on.

Shock mount bumper cage is way better than firewall mount unless you have a custom fabricated roll cage on the other side of that firewall to support the bumper when you drag it on the ground or get rear-ended.

Next step is a skidplate like:

Bolt it to the bumper cage and the pan by the torsion housing.

The mounting kit I bought doesnt have the top 2 brackets angles for the shock bolts so ill have to bend those. Joy.

So you bolted the brackets to the cage? You didnt weld them on?

Where did you get the brackets?

Bending straight ones wont be right and they will be a PITA to install.

If you weld the brackets to the bumper cage, it will be a pain every time you want to install or remove it. If you can unbolt the bumper with one bolt at each tube and slip it off the brackets, it will be so easy. If you have to unbolt the engine mount and shocks to remove the bumper, it gets much more difficult.

The brackets should each consist of a section of 1-1/4" OD tube about 6" long which will slip inside the ends of the bumper cage tubes. There should be a section of straight bar stock about 1/8" thick x 1-3/4" wide with a hole for mounting. 2 of the mounts should have the plate welded across one end of the tube at 90 degrees and have a large (like 7/8") hole in the plate to mount to the engine mount bolts which go into the ends of the frame yokes. The other pair should have the plate welded on at about a 45 degree angle across one end of the tube. These should have 1/2" holes for the upper shock mount bolts.

Some solid steel motor mounts have a pair of ears which stick out on the lower corners with a 3/4" hole in each to mount a bumper cage to. This requires welding a 3/4" hex nut into the end of each lower tube. The cage then bolts on with a 3/4" bolt through the front of the motor mount plate and into the nuts welded into the cage. The cage bars need to have the correct spread between them for this to work.

Cages USED offroad or run into on road tend to get bent and then get more difficult to R&R. Also, if you're in the rust zone, rust between the bracket tube and the bumper tubes can be a problem. Sliding the tubes on or off might require use of a rubber mallet. Using short tubes on the brackets (like 3" long) will reduce the difficulty in R&R.

Ordered mine from Chirco. The top dont bend at 45 degrees; they're straight.

Mounts for attaching to the upper shock mounts:

Mounts for attaching to the firewall:

If yours are straight barstock, they are for mounting to the firewall. The ones for mounting to the upper shock mounts are squished tubing which tends to break at the end of the squished part.

Early VWs 1960 and earlier have upper shock mounts which have the bolts pointing at each other. Later VWs have mounts which have the bolts at 45 degrees. The mounts Chirco sells may not be bent from the "Factory" so they will fit early cars, yet are easily bent to fit later cars. This easiness to bend is weakness. Better quality mounts are made of tubing and bar stock. They don't bend or break so easily.
