The Front Bumper on my 35 Standard Coupe is not straight. The passenger side is 1" higher than the Drivers side. I need to lower the passenger side 1/2" and raise the drivers side 1/2" to make it even or straight. I see no way to adjust it. The picture does not show it clearly but it's there.
Jonjet yes you can definitely see the height difference with the drivers side tire shown and the passenger side no tire viewd! A couple of possibilities 1. You could elongate all the bolt holes and that should get your 1/2 inch each side! 2. Cut the front bumper brackets and reposition till your happy then reweld! Here’s my 34 Chevrolet Standard Sports Roadster front bumper brackets that I reworked and pulled in the front bumpers for a cleaner look same as my rear bumpers!
Yes my Australian Holden Roadster brackets were correct for my 34 Roadster but I had modified and pulled the front bumper brackets in for a cleaner look! The bumper braces and bumpers are completely different from usa and canadian ones. The usa ones have a long bolt goes thru the end loop and only one bolt going thru the bumper face. The Holden AU ones do not have the loop on the end and have 4 bolts that go thru the bumper face. Here’s my 34 Chevrolet Standard Holden Roadster front bumper brackets all reworked and modified !
Also possibly a twisted frame ? bumper brackets……….you need to measure from a level ground up to a spot on the frame and do both sides L & R and see if there is a difference. If so either frame horn has a twist,  or the springs settlement  are throwing measurements off! Again on the drivers side front bumper can easily see a lot of the front tire! On the passenger side front bumper there is no view of the drivers tire! Another note possibly a big FAT person sat in the drivers side for 85 years caused early fatigue with the suspension system! LoLÂ
There is a lot of tire showing between the left fender and bumper while none visible on the right. I would be looking closely at the frame ends and the bumper mounting brackets suspecting something is twisted, a slight twist in the centre will make a big difference at the outer end. removing the brackets and swapping left for right may well fix the problem.

At first glance it appears to be only a bumper alignment problem. I agree with the advice to first check a few other measurements to confirm that it is only the relation of the bumper to the chassis and body.
My experience is that there is more than enough clearance in the various holes in the bumper, bumper brackets, and frame to allow the adjustment you need.
I used a 3 step process when I re-installed the bumpers on my car. Obviously it is best to start on a level surface with the tires inflated to the proper pressures. 1) I assembled the brackets to the frame and the bumper to the brackets with the fasteners fairly loose. The whole assembly was hanging at its lowest height. 2) I placed a jackstand at each end of the bumper and used tapered wooden shims between the saddle and bottom of the bumper to get the height I wanted at each end and get it level. I used the shims that are used when you install windows and doors. 3) Tighten the hardware in 2 steps. Snug each fastener enough to hold things in position. Then go back and do a final tightening.
This was on my '37. Based on what I have seen the bumpers on your '35 attach in a similar manner. At each side of the bumper there are 2 brackets that attach to the backside of the bumper and the front of the frame rail.
In fact everything was so loosy-goosy that I had trouble getting things together initially. I figured out that I needed to attach the brackets to the frame first and then the bumper to the brackets.
This is true on a 35 Master but not on a 35 Standard. A 35 Standard only has one Bracket on each side. But I think I solved the problem. Yesterday I measured both sides from the Frame to the Floor in a couple of places, they seemed to be the same. I loosened both bolts that hold the Bumper Bracket to the Frame Horns. Today I loosened those Bolts and also the bolts that hold the Medallions on. Then I used a Floor Jack under the Drivers Side of the Bumper and raised it to where it was level and tightened all four bolts and it's almost perfect. Sometimes I'm really stupid and just don't think but I think I solved the problem. Thanks for all your help.
I had to chuckle when I read your initial post. I am helping a friend get a '49 3100 AD pickup back on the road. We were really having a tough time making the front bumper fit correctly and look good. We measured and measured, used levels on the car and bumper, and made adjustments until we were tired of it. No matter what we did it did not look right in relation to the fenders. And it was very noticeable.
Then I asked my friend how much repair he had done to the fenders. Turns out it was quite a bit. We finally discovered that the real problem was a severe mismatch in the profiles of the fenders. The great part is that this area will be completely hidden when the license plate is installed!! Sometimes you get lucky!
