    Use 2 jacks , one to jack up at the frame
    Then use a scissor jack between the frame and spring/axle tube [depending on where the bumpstop is]

    It's one of those things, like running open headers...sometimes you have to have a little common sense.

    Now had you searched here beforehand, you'd have come across this same issue...heck I even knew about it and don't ever plan to have a vehicle I'd want to put blocks on.

    A guess a little more perspective on my situation. This car is entered in the 2018 Great Race (a vintage car rally) and is being prepped for that event. The lowering was to gain a little better handling. I figured a mild 2-3 inch drop should not be that big of an issue. I be wrong....:)

    So, dealing with a long delay at the side of the road to change a flat tire is not a good thing. Some road hazards just don't give you a small hole that can be sealed with gel and then deal with it later during the over-night stops.

    All good suggestions. I'm looking into a smaller cross section tires like a 195/70x15. The nice thing about the newer metric tire sizing, you can calculate the dimensions from the tire size rather than digging through vintage tire guides.
    I also, plan to roll the fender edges and maybe push out the fender slightly.

    Actually finding out details on lowering was really not that easy with the way the search feature works. What is really annoying is that the suppliers of these lowering parts don't seem to mention the tire issues. They give you warnings about other modifications that may or may not work on your particular car....

    Mark, not sure what style blocks that you have but you may be able to cut them down 1" or so and try that .

    The Great Race really doesn't require "better handling" as the speeds are moderate. Accurate timing and navigation over each stage are the keys. Modifying your car in such a way to inhibit 'corrective measures' seems counterproductive. Modifications for reliability are more useful. (I participated in THG some years ago)

    My '50 Ford runs 205/75/15 tires all the way around with 3" blocks and I have no problems at all getting tires on or off. Maverick rear on 15x6 Ford Ranger truck wheels (covered). I jack up one side at a time.

    I had a buddy that had a Chevy 2 with a narrowed rear, but not widened wheel openings, and sat kinda low. For him to get a tire on or off had to take out the rear leaf spring bolt and undo the shock to let the rear end hang down far enough to let the tire clear the opening. Kind of a pain, but it sure looked cool.

    Change the block one that does not lower the car so much.

    First check to see if the shock is not limiting the drop, if so disconnecting the bottom bolt should give you clearance. Ralphie
