Why you should consider a professional:
* Complexity: The process involves intricate steps, including working with delicate fabric, precise alignment, hydraulics (if equipped), and potentially replacing worn parts. Improper installation can lead to leaks, poor fit, and damage to the top mechanism.
* Specialized Tools: Specialized tools are required for proper installation, including specific clamps, tensioning devices, and potentially a sewing machine capable of handling heavy-duty canvas.
* Time Commitment: Expect to spend many hours, potentially days, on this project, even with experience.
* Potential for Damage: Incorrect installation can damage the top material, frame, or mechanism, leading to costly repairs.
If you're determined to do it yourself, here's a general overview (this is NOT a comprehensive guide):
1. Gather Materials and Tools: You'll need the convertible top itself (ensure it's in good condition), new or refurbished bows (the metal supports for the top), new or repurposed weatherstripping, hydraulic pump parts (if necessary), sewing machine, heavy-duty thread, various clamps, specialized tools for the convertible top mechanism, and possibly new hydraulic lines. Reference a shop manual specific to your 1972 Oldsmobile Cutlass convertible.
2. Prepare the Car: Clean the car's convertible top frame thoroughly. Check the frame for any damage or rust that needs repair. You'll likely need to remove any interior components that hinder access to the frame, such as rear seat panels and possibly even parts of the interior trim.
3. Install the Bows: Carefully attach the bows to the frame, ensuring they're aligned correctly. This is a crucial step, as misalignment will result in a poorly fitting top.
4. Attach the Top Fabric: This is the most challenging part. You'll need to carefully attach the top material to the bows and frame using the proper stitching and tensioning techniques. Ensure the fabric is stretched evenly to prevent wrinkles and tears. Consult a shop manual or find instructional videos specific to convertible top installation.
5. Install the Weatherstripping: Proper weatherstripping is vital to prevent leaks. Install it carefully around the edges of the top frame.
6. Test the Hydraulic System (if applicable): If your Cutlass has a power top, carefully test the hydraulic system to ensure it's functioning correctly. This might require troubleshooting and repairs.
7. Reinstall Interior Components: Once the top is installed, carefully reinstall all the interior components that were removed.
Resources:
* Shop Manual: A 1972 Oldsmobile Cutlass convertible shop manual is invaluable. It will provide detailed diagrams and instructions.
* Online Forums: Search online forums dedicated to classic car restoration. You might find helpful advice and tips from experienced individuals.
* Convertible Top Specialists: Consider contacting companies that specialize in convertible top repair and installation. They have the expertise, tools, and materials to do the job correctly.
In short: Unless you have significant experience with automotive upholstery and convertible top mechanics, strongly consider taking your 1972 Oldsmobile Cutlass to a professional. The cost of professional installation will likely be less than the cost of repairing mistakes made during a DIY attempt.
