I started making a GM HEI distributor for it and when I mocked it up on the engine block I realized I’d better check for clearance under the hood before getting too far along.
That meant I needed to first address the transmission cross member since on my car the factory one is modified and installed 180 degrees to accommodate the 700R4.
I sawed the cross member out of the subframe and filled the two holes. I drilled and pinned it for a positive fit. I also began filling in the top of the subframe with filler. (The orange one is the way the kit comes.)
After test fitting this subassembly into the body/chassis I can see it does have enough clearance and is similarly tight like the real counterpart.
