(flared fenders) than most other replicas. Kind of a cross between the original wide hip and narrow hip bodies. My total outside dimension of the rear fender lips is 68".

My rear frame rails have a 35" outside width dimension.

My rear axle is 54 3/4" wheel mounting surface to wheel mounting surface.

Could be your rear wheel width and offset are very different than my original Sunburst wheels.

Greg - the ERA dimension from wheel mount surface to wheel mount surface is 53.64 inches. I will have to crawl under it to measure the frame outside dimension but I suspect it is more than 35 inches. I actually chose to go with the 9-1/2 inch wheel since the extra width over the 7-1/2 inch wheels (as set up for an ERA) is all, or mostly to the outside, which tends to place the tire thread and inner sidewall further to the outside. With 7-1/2 inch wheels I probably could not have fit a 2-1/2 inch tailpipe.

ERA does have an option for a slightly wider track in the rear for those who want to run 7-1/2 inch wheels in the rear but don't want the sunken into the wheel wells look that the wide hip body results in.

You have a nice set up. I have my exhaust system back from the ceraimic coating place and I hope to get it hung in the near future.
