I've worked on my Maverick twice in the past two years.
Once, about 6 months ago, and again today.
Both times, I've been focused on finishing the rear axle.
I was able to find a set of Explorer disc brakes, and get them mounted up. The brakes did require a special-made spacer though- a 3 1/8" OD and 2 1/8" ID washer, to ride between the backing plate and wheel bearing.
I decided it was better to save my back some and work on the table today:
The next steps are to install the axle in the car, and get it rolling. That's going to lead into retro-fitting a Grenada front end (front disc brakes) onto the car... which is available from a kit thankfully.
After that, I'll be mocking up my transmission mount... then it'll be onto an engine!
