Need help from lowering experts

[cj847]

I have a 68 that I bought already lowered. Needless to say, I don't know for sure what I have. My concern is the front suspension. I think it is 2.5" spindles and about an inch off of stock springs (or could be aftermarket) They measure 8.75 to 9" installed. This is a very mild lowering compared to what is on this board. Tires are 235/75/15. Shocks are new but are cheap blue monroes.

Here is the problem. When I drive over a "hoop de do", the front suspension doesn't bottom on the bump stops, it bottoms out on top of the tire. This is very dangerous if you are not expecting/slowing for a hoop de do. PS> the bump stop is missing on the side that bottoms first. But, a lot of rigs on this board have cut their bumpstops and mounts off.

Are most mildly lowered truck running aftermarket or no inner fenders?
