3/25 (Day 3)...Starting the Day

With the great progress this weekend (in just 2 days), we started the morning a little later, and first enjoyed a great breakfast at a local country cafe. On the list for this morning...installing a home-brew 1" body lift to gain some additional clearance in a couple places, making custom mounting brackets for the intercooler parts, etc.


Here's our front suspension, steering set-up, and our RockSolid Steering Sector Shaft Brace & Track Bar.

The finished Metalcloak front suspension.


Driveshafts are installed, and exhaust is complete.


Custom air intake (including mass air flow sensor) built with misc. parts.


Atlas shifters installed!


3/24 progress (as of 4:15 p.m.)

Fastback soft top is now installed. There's no photo showing it, but the 1" body lift is also installed.)

Fitting a custom-built steering shaft (among other small things in the engine compartment).
