Can anyone tell me if a 33-34 wishbone is longer then a 36 wishbone? I'm building an av8 with a 40 flatty, 39 trans with a tardel crossmember and I didn't want to split them. If i use the 36 wishbone comes up about an inch shy of the spring. the radiator is already crowded so I really don't have room to move motor, trans forward. I read an article in rod and custom on a prewar 29 roadster and they say use the 33 wishbone. Any suggestion's?
If you measure from the center of the bottom hole at the clevis to weld at the forged yoke the measurements are as follows. 33-34 are 40" and 35-36 are 45" inch.
The 32-34 wishbones did not end in a point. They needed to spray out so to clear the engine pan. I can't see how a 36 would work and use the ball mount in the K member. The 33-34 wishbones are 2 " shorter than a 32 and are the standard to use in a 32 frame and K member. If you have a 33-34 wishbone, I would weld in some sections to lengthen the legs. The legs are 2" longer. A Model A wishbone is the same on the end except bowed. You could flatten the bow and weld in the A end for less welding.
Not really. You would end up with the radiator 2" ahead of the front crossmember and the crossmember would have to move back so the spring would go in it. The K member location is determined by the rear end and the front crossmember location is determined by the wishbone.
The 32 bones work just fine. The legs are 2" longer. Like I said, just add 2" to 33-34 bones right at the weld at the rear yoke.
33/34 is to short and 32 is to long at least if you don't want to have other issues. My 33/34 wishbone has had 1-3/4" sections tig welded in after we split the factory welds at the yolk. Extensions where turned out of solid round stock with a nice little step that fit into the old parts then the centre was drilled out. I have lots of photos but they are to large to post here. It all turned out very nice.
Thank's for all the great info! I think I'm going to use the 36 bones with the model a yoke like 296 v8 suggested. Doing this for 2 reason's 32 wishbones are expensive, I already have the a 36 bone and an a bone. Also the 36 bones work well with the 39 spindle's I'm going to use. My question is how critical is the camber adjustment,if so can I just stick a degree finder to it, and what should it be? Do I have the weight of the car on the suspension to make my measurement's?
Camber should be about 6 degrees when done. Get your engine/trans in, body on with all wood and interior for weight, choose your tire rake. Then check your camber with a magnetic degree finder set flush on the upper and lower flanges of the axle perpendicular to the floor on a level surface. You may have to pie cut the wishbones near the yokes for the perch pins to get your camber correct. BTW, '32 bone is 47" from center of ball to center of perch pin yoke. That's the correct measurement you need for your application. Ask me how I know.
Am I missing something here? The Tardel/Bishop book....they use a 33-34 wishbone with the Tardel K member in the stock A frame.
I think that may be a misprint. Should be a 32 wishbone. Sent from my DROID device using the TJJ mobile app
