88 Cradle FIxture for Engine Swaps & Tubular Cradles (Page 1/1) fieroguru AUG 02, 03:04 PM This is the cradle fixture I built in 2009 and have used for every engine swap and tubular cradle I have built since then. I am not getting out a fieros or making custom parts, but I am upgrading to professional fabrication table that will be large enough for the front suspension and I will be remaking everything for the new table for the rear cradle as well. I will not need this going forward and figured someone could use it increase the level of precision in engine swap placements. While this was designed and built for the 88 Fieros, since the 4 cradle bolt locations are the same as the 84-87, it will also work (and I have used it) for the 84-87. I just never took the time to make the plates for the suspension locations. $1,500 OBO picked up at my house - 61822. It was made with 4x4x1/4" I-beams, 3" channel, and 1/2" mounting plates. When I built it, Will asked if I had degree in over-engineering! When it was first built, it also had 4x4 I-beams stacked in an X pattern on the bottom to ensure it remained flat while welding. Sometime in 2012 I removed the lower X-portion and have just used the top portion since. All the 3/8" locating holes were drilled with the plates clamped to the fixture so they precisely locate the 1/2" plates. With this design, you can add spacers (I used 1/2" nuts) between the plates and 4x4 base to raise everthing relative to the 4x4 base, this allows building the tubular cradles to sit lower than the stock cradles and allows the drivetrains to be installed quite low in the engine bay. It has: 6 1/2" steel plates to pickup all the 88 cradle bolt locations as well as all the suspension locations. 2 2x2 angles that are the guide rails for clamping tubes to for the tubular cradle fabrication. 2 1/2" plates in the center are for the LS4 crankshaft and F40 supports. These will positon and support the LS4/F40 drivetrain above the cradle for mount fabrication. This will place the LS4/F40 in the exact same location as my current LS4/F40/Turbo swap. Here are some pictures of it in use. You can also look at any of my build threads post 2009 and see more pictures of it in use.
