C4 owners rejoice! Tom Gaspar the original designer and builder of the Anti Flex Support Bar is now selling through Astro Tops. It is available on Ebay. This is the bar originally featured in Corvette Fever back when. It bolts on in place of the C4 roof panel and gives excellent support while driving. As stated Anti Flex. https://www.ebay.com/itm/C4-1989-96-...MAAOSwxQJbCHRo

$650....pricey

Yeah but well worth it. I've owned two from Tom Gaspar, one for my '94 and one on my '95. Both were well made and performed as stated. It really puts the car back together even better then when the roof panel is on. Open air driving without all the flexing, creaking and twisting that C4's are known for.

I’ve had one for about 8 years I believe. Bought new from Tom, they were at the time made to order and the build quality is top notch. The powder coat looks new to this day and given that it’s black, my car is black and my interior black it looks practically like a factory option. It fully resolved the wobbly feel with the targa off and I believe the car feels stiffer with this bar in place than with the acrylic top.

Does what its advertised to do

Agree with above replies. Really stiffens up car with targa off. Quality is excellent and adjusts to fit well.

If you call Tom, the price is 475

Mine was $475 plus some shipping.

Went

I just purchased a used 1990 Acrylic top for my 95. It's in pretty nice overall shape, with excellent weatherstripping and only a few minor scuff marks on the lens. I haven't tried to polish it up yet, but it shouldn't need much. Now for my question:

My old top lens is cracked in two places, and the weatherstripping is completely shot. The frame looks to be in excellent condition (no visible cracks). I was thinking of taking the lens out and heliarc welding in a center brace assembly and try to make my own AFSB bar. Has anyone tried this? I'm not sure what my old top is worth on the market, since it would need a new lens and weatherstripping. Might be an interesting project. Any thoughts?

Regards,
John

I'm thinking that is a good idea to try since the top needs work. My guess is that the lens provides some kind of structural support itself as part of the entire top and an empty frame will flex, but if you can reinforce it as you say, then you might eliminate some slop. Maybe two braces instead of just one? Maybe an X?

The thing that bothers me about any of the aftermarket targa bars is that they look like a roll cage and you cannot get the top on the car without removing them.

This topic has me curious and I found a guy that makes a soft top kit for replacing the stock top. He also has a center brace that bolts in.
