OK, here's the problem. I'm installing a '95 Riviera L67, and the throttle cables run toward the trunk. This means my throttle cable is about 2 ft short. I've got a plan to extend the V6 throttle cable so it will reach, but it's not a great solution. I started thinking I could change out the throttle body for one that has the throttle cables running toward the driver's fenderwell.

My first stop was Rockauto.com, where I researched the Throttle Body Gasket for the Riv. Thought that might lead me to a throttle body that would at least fit the SC. Turns out the throttle body gasket was only used on 94 or 95 cars, which I guess makes some sense ( change in the SC, HP increase to 225). Turns out the TB on 94-95 Park Avenue, 94-95 Bonneville SSEI, 94-95 Olds 98 and 95 Olds 88 use the same gasket. Some of the pictures I've been able to see on the net ( EBAY!) indicate that this might work for me. but I thought I would ask the folks here with experience whether I should continue down this path, or just extend the cable...

I've got a Part Wanted ad in the Mall, just in case this might work.

Thanks for the photo. I hadn't tried routing the cable that tight to the engine. I tried it on mine, and I can get it to reach, but it will be a very tight bend radius at the bracket. It is also rubbing against the EGR pipe in the rear, as well as the exhaust heat shield ( guess I could heat sleeve it?) Your's seems to have a little more slack at the bracket, and I'm wondering if that is a 4 cyl cable. They are supposed to be a little longer than the 6 cyl models ( 102" vs 96"). Wonder if that extra 6" would make a big difference ( $50 bucks worth).

Not my engine or picture. I just googled it.

Yes I believe it is the 4 cylinder throttle cable.

Thanks all. Bit the bullet this morning and ordered a new cable. Best solution!
