Right off the bat, our installers experienced some clearance issues. For example, the factory GM HEI unit interfered with the Dynacorn Gem's firewall. However, a quick thinking Maxwell realized that an MSD Pro Billet HEI is slightly smaller. A quick substitution immediately rectified the problem.
Another of the pleasing features about the Chassisworks F-Body sub frame is that the manufacturer provides the builder with a pair of 5/8-inch threaded frame alignment pins, invaluable items for all important pre-assembly.
This is how our 99% completed Chassisworks front sub frame looks like from the rear of the car once trial-fitted in place.
Next, Maxwell and company measure straight up from the shifter location of the TKO 600 transmission, and cut a "shifter slot" measuring approximately 1-1/2 x 3-inches in the center of the transmission tunnel.
Woods trial fits the Alston sub frame connectors (p/n 5601-20) up to the underside of our Dynacorn Reproduction Bodies '67 Camaro uni-body.
In the process, some seat clearance issues were addressed with the floor pan. A couple of slots were cut prior to bolting up the sub frame connectors.
With sub frame connectors fitted in place, the mounting holes are drilled.
